Fix IMAP delete handling

When a message is flagged as deleted on the server, but is not yet purged,
we'll see it syncing down with a deleted flag. This change treats that
condition as if the message has been fully deleted.

Also fix a copy/paste error for cleaning up the message modification tables.
