    window-actor: Set actor as compositor private in window before the surface
    
    In MetaWindowActor creation we're setting the compositor private (i.e. the
    window actor itself) of a window before creating the surface actor, and so
    passing to the it a window without its compositor side set.
    
    Since the surface actor might use the parent actor, set this before updating
    the surface.
