clutter: Force an allocation on clone source if necessary
Since commit 0eab73dc
, actors are only allocated when they are actually
visible. While this generally works well, it breaks - because of *course*
it does - ClutterClones when the clone source (or any of its ancestors)
is hidden.
Force an allocation in that case to allow the clone's paint to work as
intended.
