Fixes background animation on dismiss.

Browse Source 
This change modifies the logic in
NotificationStackScrollLayout.updateFirstAndLastBackgroundViews() which
determines if the first or last visible notification row has changed.
The "old" values were being read after the changes were applied, meaning
that the change was never detected, so an animation was never started.

Test: manually
