Subject: [PATCH] Stop composite timer when Workspace gets destroyed

On Wayland tear down the Workspace gets destroyed before the Compositor
gets destroyed. If the timer fires in that area, the Compositor would
crash. It's not possible to start the timer if the Workspace is
destroyed, thus it should also be stoped on Workspace destroy.
