link2xt c14f45a8f5 fix(imap): avoid IMAP move loops when DeltaChat folder is aliased ...

Some Dovecot servers are configured
to alias "INBOX.DeltaChat" and "DeltaChat" to the same folder.
In this case Delta Chat moves new emails from "INBOX"
to "DeltaChat", but then discovers the same mail in "INBOX.DeltaChat"
and tries to move it to "DeltaChat" again.
Each time a MOVE command is issued to move the message
from "INBOX.DeltaChat" to "DeltaChat", the message gets a new UID.

To prevent such IMAP move loop between aliased folders,
we do not move the message if we have already seen it on IMAP,
i.e. we have its Message-ID in the `imap` table.
Note that we do not use `rfc724_mid_exists`,
because it checks the `msgs` table and would consider
BCC-self messages seen even before we see them in the Inbox,
preventing their move to the DeltaChat folder.

Duplicate messages and messages without Message-IDs
are not moved anymore, but this is better
than having an infinite move loop.
