Fix bugs around inflated child fragments

Framework edition

* Ensure that a fragment that has had its view destroyed has a chance
  to recreate it.

* Clear mInLayout after views are destroyed

* Make sure that when a fragment is restored from the back stack and
  reinflates its view that child fragments from fragment tags are
  reconnected properly.
