Fix bug where QS tiles appeared behind keyguard

Animations must be run when closing QS during reset. Otherwise, keyguard
can enter a bad state where QS remains visible even though it should be
hidden.

Test: Open QS, tap user icon, double-tap blank area, ensure you are
      taken back to the lock screen and that the UI looks normal
