Change the leave message on 333 MUC status

Following the discussion in https://prosody.im/issues/939, and in the
prosody@ room, this patch reflects the fact that the 333 status is not a
normal leave, and displays the following if it is included:

> "badger has left the room due to an error (reason)"
