Tim Culverhouse 0c85b5a6cf msglist: remove invalidate from commands which remove messages
Archive, delete, and move all remove messages from the message store.
The commands themselves invalidated the message list. The message list
was also invalidated for every MessagesDeleted message received. Remove
the call in the command logic to reduce redraws of the message list
