Fix regression with drop targets not being visible.

- This happened because the RecentsView had the same priority as the
  touch handler, which updates the visible dock states, which RV uses
  to determine what to draw, resulting in the first time after rotation
  to not show the right targets.  The touch handler should now have a
  higher priority than the view that depends on it.
