[DO NOT MERGE] Prevent hotseat touch hijack
Currently in AllAppsContinerView#onInterceptTouchEvent we check if a
touch event is in bounds of RecyclerViewFastScroller and set
mTouchHandler so the scroll bar handles onTouchEvent. However, if a user
performs a back gesture from the right side (which overlaps with the
scroller) and returns home, touches to the hotseat get intercepted.
