UIs now display green checkmark in a profile
if the contact is verified.
Chats with key-contacts cannot become unprotected,
so there is no need to check 1:1 chat.
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.
This change introduces a new type of contacts
identified by their public key fingerprint
rather than an e-mail address.
Encrypted chats now stay encrypted
and unencrypted chats stay unencrypted.
For example, 1:1 chats with key-contacts
are encrypted and 1:1 chats with address-contacts
are unencrypted.
Groups that have a group ID are encrypted
and can only contain key-contacts
while groups that don't have a group ID ("adhoc groups")
are unencrypted and can only contain address-contacts.
JSON-RPC API `reset_contact_encryption` is removed.
Python API `Contact.reset_encryption` is removed.
"Group tracking plugin" in legacy Python API was removed because it
relied on parsing email addresses from system messages with regexps.

otherwise, by tuning down the email addresses,
one does not really has and idea who is SELF.
maybe the dialog is the only way at the end to get the transport
adresses of contacts,
this is unclear atm, this PR fixes the issue at hand
SecureJoin and importing a vCard are the primary
ways we want to support for creating contacts.
Typing in an email address and relying on Autocrypt
results in sending the first message unencrypted
and we want to clearly separate unencrypted and encrypted
chats in the future.
To make the tests more stable, we set up test contacts
with vCards as this always immediately
results in creating a single encrypted chat
and this is not going to change.
