[Icon Item] Don't animate from previous pixmap when it has been invisible

We have a lot of reusable singletons that are just hidden when not needed, such
as the OSD. IconItem, however, will always fade from the previous state, even if
the previous action happened minutes ago.

This fixes for example changing the volume and then later changing the brightness
where you could see the OSD animating from the volume icon.
