Wait for notification shade to redraw on orientation change 

It was skipped to reduce rotation latency. But it may look
flashing if the top app is redrawn much faster than the
notification shade or the background colors are not similar.

Bug: 194610242
Test: Expand notification shade and rotate device while the
      foreground app can handle orientation change quickly.
