This commit addresses a race condition when showing the message drawer and opening the settings page from the Message preferences page. In that situation, the message/edit.php page calls the message_drawer_helper.showSettings function, which publishes a request to show the drawer. In some conditions (notably faster machines, or after MDL-66107) this event is fired before the message_drawer.init has listened to it. The solution here is to delay firing of the event until the drawer announces itself as ready. This ensures that the event is subscribed to before it is fired.
