tests: Add a test for ClutterActors stage_views() API

Browse Source 
Test that the stage-views list of ClutterActor is correct when moving an
actor, reparenting it, or hiding an actor up the hierarchy. Also test
that the "stage-views-changed" signal works as expected.

Don't test actor transforms for now because those aren't supported yet.
