Rebind recycler views if launcher activity restarted

Bug: 185038312
Test: manual
TL;DR;;
What was attempted but was too much refactoring of the code.

Failed attempt #1: try re triggering the search.
This was not trivial as SearchSession object is yet created.

Failed attempt #2: Restoring AdapterItems in AlphabeticalAppsList
This meant AdapterItems class and also it's children
had to extend Parceleable object.

Ultimate fix:
Original issue of dupe view id among slice and work recyclerview
should be fixed. And restoring should just work.
