segmentation fault when checking for mail

[Allen Lowe]

If I mark a message as read on the server and move it to the trash on the server, Postler will crash with a segmentation fault on the next sync.

turns out it happens if I ever move any message to the trash on the server. My account is Gmail, if I move any message from the inbox to trash in the Gmail web interface, Postler segfaults on the next sync

We need to check if the new message is null. A message marked as deleted, like in this case, would not show up in the message view hence it returns null.
