Encrypted message may create unencrypted groups
if the message does not have a Chat-Group-ID.
This can happen if v1 client sends an encrypted
message to opportunistically encrypted ad hoc group.
In this case `from_id` corresponds to the key-contact,
but we should add address-contact of the sender
to the member list.
The icon is mainly used to identify unencrypted chats
in the chatlist where encrypted and unencrypted chats are mixed.
It is used for group chats rather than only for 1:1 chats
with address-contacts.
We don't want to prefer returning verified contacts because e.g. if a bot was reinstalled and its
key changed, it may not be verified, and we don't want to bring the user to the old chat if they
click on the bot email address. But trying to return accepted contacts increases security and
doesn't break the described scenario.
If an address-contact and a key-contact were seen at exactly the same time, that doesn't necessarily
mean that it's a random event, it might occur because some code updates contacts this way in some
scenario. While this is unlikely, prefer to look up the key-contact.
Work around possible checkpoint starvations (there were cases reported when a WAL file is bigger
than 200M) and also make sure we truncate the WAL periodically. Auto-checkponting does not normally
truncate the WAL (unless the `journal_size_limit` pragma is set), see
https://www.sqlite.org/wal.html.
- It's obvious that addresses are needed to add contacts, so `_by_address_list` looks excessive.
- The function only looks up `SELF` by address.
- The name was confusing because there's also `lookup_key_contacts_by_address_list()` that actually
looks up key contacts by addresses (not only `SELF`).
- Added import-vcard and make-vcard commands to deltachat-repl. These
wrap the corresponding import_vcard() and make_vcard() operations from
src/contact.rs. Each command takes a file path argument specifying the
location of the vCard file to be read or written. The make-vcard command
takes one or more IDs to write to the file.
- Documented commands in "Using the CLI client" section of README.md.

The info will look like:
```
debug_assertions=On - DO NOT RELEASE THIS BUILD
```
or:
```
debug_assertions=Off
```
I tested that this actually works when compiling on Android.

This adds a test for https://github.com/chatmail/core/pull/7032/.
The crash happened if you received a message that has the from contact
also in the "To: " and "Chat-Group-Member-Fpr: " headers. Not sure how
it happened that such a message was created; I managed to create one in
a test, but needed to access some internals of MimeFactory for that.
I then saved the email that is sent by Alice into the test-data
directory, and then made a test that Bob doesn't crash if he receives
this email. And as a sanity-check, also test that Bob marks Fiona as
verified after receiving this email.
Sort recipients by `add_timestamp DESC` so that if the group is large and there are multiple SMTP
messages, a newly added member receives the member addition message earlier and has gossiped keys of
other members (otherwise the new member may receive messages from other members earlier and fail to
verify them).
This PR adds a test to reproduce a bug raised by @adbenitez that peer
channels break when the resend feature is used.

This should fix https://github.com/chatmail/core/issues/7030; @r10s if
you could test whether it fixes your problem
The crash happened if you received a message that has the from contact
also in the "To: " and "Chat-Group-Member-Fpr: " headers. Not sure how
it happened that such a message was created.
Previously, chat protection was only removed if the chat became an
email-chat because the key-contact has a different email, but not if the
chat became an email-chat for a different reason.
Therefore, it could happen that the migration produced a protected,
unencrypted chat, where you couldn't write any messages.
I tested that applying this fix actually fixes the bug I had.
