Fix stale nested prefetch data leaking out after notifyDataSetChanged

Bug:36558253
Test: adb shell am instrument -w -r -e debug false -e size small android.support.v7.recyclerview.test/android.support.test.runner.AndroidJUnitRunner

Switches notifyDataSetChanged to always discard all cached views so
content in the cache is always trustworthy.

Also fixes a case where GapWorker attempts to prefetch inner items
before the containing RecyclerView's data is bound.
