[Contextual Edu] Not update edu stats when swiping down all apps panel

It should only update edu stats of home gesture when user swipe up to go home. It is already handled in AbsSwipeUpHandler.
This change avoids updating edu stats when users swipe down the all apps panel as it is not considered as home gesture.
