All taps under max double tap timeout are quick taps

When tapping rapidly on the overview button on a recents grid device
(like tablets), users might tap very quickly that would have triggered a
elasped time under the min double tap time (40ms) which would cause the
button to not be a quick tap. Removing the check allows all taps under
the max double tap timeout to be a quick tap. Then quickly tapping the
overview button would not confuse alt-tab with resume same task
functionality.
