Fixing bug where widgets would go dead after moving to another screen

-> A memory optimization was causing AdapterViewAnimator to give up its
   reference to its adapter, rendering the widget dead.
-> Did testing, and it doesn't appear that this optimization was
   making a difference, so it appears safe to remove.
