Fix empty password for provisioned account

Passwords can't just be `null` but also an empty string. The code did
not handle that properly. Now checking against `emtpy` so both `null`
and `''` trigger shortcut evaluation and prevent decrypring of an
invalid value.

As a precaution for the database message cache it make sense to have a
CLI command to diagnose the capabilities and size of an IMAP account in
case of slow or failing syncs.
