clutter/stage: Emit after-paint after painting

Browse Source 
ClutterStage:after-paint is supposed to be emitted after all
painting is done, but before the frame is finished. However,
as it is right now, it is being emitted after each view is
painted -- on multi-monitor setups, after-frame is being
emitted multiple times.

Send after-paint only once, after all views are painted and
before finishing the frame.
