That's a bug which @Simon-Laux and probably also @hpk42 had, where one malformed incoming (Spam-) mail blocked the receiving of all emails coming after it.
The problem was that from_field_to_contact_id() returned ContactId::UNDEFINED, and then lookup_by_contact() returned Err.
* Treat multiple From addresses as if there was no From: addr
* changelog
* Don't send invalid emails through the whole receive_imf pipeline
Instead, directly create a trash entry for them.
* Don't create trash entries for randomly generated Message-Id's
* clippy
* fix typo

If we fetch messages out of order, then f.e. reactions don't work because if we process a reaction not yet having the corresponding message processed, the reaction is thrown away.
* allow deleting referenced contacts in UI
we are quite often getting requests of users
who want to get rid of some contact in the "new chat" list.
there is already a "delete" option,
but it does not work for referenced contacts -
however, it is not obvious for users that a contact is in use,
esp. of some mailing list or larger chat, old contacts, whatever.
this pr revives an old idea [^1] of "soft deleting" referenced contacts -
this way, the user can remove the annoying entry
without the need to understand complicated things
and finally saying that deletion is impossible :)
once the contact is reused, it will reappear,
however, this is already explained in the confirmation dialog of the UIs.
technically, this pr was simpler as expected as we already have
a Origin::Hidden, that is just reused here.

* update rust doccomment
* update changelog
* avoid races on contact deletion
chats may be created between checking for "no chats" and contact deletion.
this is prevented by putting the statement into an EXCLUSIVE transaction.
* fix failing python test
Note that `IMAP IDLE protocol timed out` was previously
added to the wrong error: not the timeout error (first `?`)
but actual error happened during IDLE, such as a network error.
