SysUI: Check swiping progress before collapsing KBA

Collapsing the KeyguardBottomArea while a swipe is in progress causes
the window to collapse to a smaller size and cut off the circular
animations from the affordance views.  Luckliy there is a method we
can call to see if we are in such a state, so let's use it.
