actor: Use fixed positioning for allocate_preferred_size

Browse Source 
clutter_actor_allocate_preferred_size is supposed to use the fixed
position of an actor. Unfortunately, recent refactorings made it so
that it accidentally used the current allocation. As the current
allocation may be adjusted by the actor, or have been previously
allocated in a strange spot, it may have unintended side effects. Use
the fixed positioning of the actor instead.

This fixes weird issues with margins colliding with
ClutterFixedLayout, causing strange offsets on relayout.
