appDisplay: Clear animateLater callbacks when unmapping

In some situations we could end up not with lingering 'view-loaded'
handler. This could result in delayed spring animate-in being initiated,
e.g. after a minute after the activities overview was already closed.

Fix this by removing any lingering signal or later handlers when
unmapping.
