    clutter/actor: Alway call queue_relayout() when showing actors
    
    clutter_actor_queue_relayout() detects whether a parent has the
    NO_LAYOUT flag set by itself and then queues a shallow relayout for us.
    There's no need to duplicate that logic when showing actors, so simply
    call clutter_actor_queue_relayout() and let that handle it.
