Fix animation slowdown when splitting from All Apps

This patch fixes a tablet bug related to splitting from All Apps. Splitting from AllApps was playing a very slow animation.

The bug occurred because there was no case set in QuickstepAtomicAnimationFactory for animating from the ALL_APPS state.

Fixed by setting the appropriate case in QuickstepAtomicAnimationFactory.
