    messageTray: Remove deprecated code
    
    Originally the Source method for showing notifications was "notify",
    which had to change when turning it into a GObject subclass to not
    clash with g_object_notify().
    
    That change happened during the 3.36 cycle, so extensions have had
    two releases (a year) to adapt to the replacement. That seems long
    enough, so remove the deprecated compat code.
