Fixed animation breakage when QS area tapped during expand/collapse

- shade would instantly expand when QQS area was tapped while shade
collapsing; now the touch interrupts the collapse and the user can move
shade around, and shade will close/expand on release as normal
- same problem fixed for collapsing shade from full QS
- fixed QS flickering then instantly expanding when tapped while
collapsing to QQS - new behavior is the same as above
- fixed choppiness when swiping to expand QS while it is collapsing
to QQS
