Fixes Issue 963

Browse source 
MessagingController was calling the MessagingListener twice for
deleted messages.  By the time the second call was made, some
Activities already had removed the message holder, so a null holder
was being put on the list.

This change should prevent the double calls, and adds protection
against have the MessageList MessagingListener called with a message
that is no longer in the MessageList.

Also, some logical cleanups.
