bugfix: thread correctly in resumed/killed draft messages

the entire thread was being deleted because of UpdateManager changes.
now there are two signals: deleted and single_message_deleted, the first
for thread deletion and the second for draft message removal, and
ThreadIndexMode handles them correctly.
