Handle a clone of an actor with an unmapped parent

Browse Source 
If we are cloning an source actor with an unmapped parent, then when
we temporarily map the source actor:

 - We need to skip the check that a mapped actor has a mapped
   parent.
 - We need to realize the actor's parents before mapping it,
   or we'll get an assertion failure in clutter_actor_update_map_state()
   because an actor with an unmapped parent is !may_be_realized.
