Fix text overlap issue when flinging in ManageApplication

Browse Source 
The issue is we have a background handler to find app size and set to
summary asynchronously. When flinging quickly, the view being request to
update by the background handler could be scrolled off screen already.
This change forces onPackageSizeChanged update to only happen when it's
not scrolling.
