gtk-demo: Fix revealer demo
This only used by luck before. We are changing a property from the
::notify handler for that property. Now that GtkRevealer is notifying
the property when it stops animations on unmap, we end up in a life
lock situation where we never make it out of the notify queue.
Fix this by not restarting the animation if the widget is unmapped.
