Changed swipe up from QQS over keyguard to return to keyguard

Previously, swiping up from QQS over keyguard was treated like
any swipe up on keyguard, simulatenously dismissing QQS and bringing
up the bouncer/dismissing keyguard if screen is unlocked. The latter
case caused an undesireable transition where launcher was visible
where the notif scrim should be.
