Fixes quickstep swipe up animation being stuck

When swiping up, sometimes launcher will tell sysui that recents has
started but the user's finger is still on the screen, when user lifts
off the screen, recents started and nav gesture will not get any events.
Now we always run the gesture code even if recents has started so
sysui can proxy action up to launcher and complete the animation.
