[SB][Notif] Make sure re-tapping notif chip hides HUN immediately.

I originally implemented this behavior in ag/31139202 and it seemed like
it worked because the minimum timeout for the HUN was 1 second. But
later in ag/31744914 we updated the minimum timeout for chip HUNs to be
3 seconds, which means re-tapping the chip no longer worked if you did
it within the first 3 seconds.

This CL ensures we remove the HUN immediately if the user re-tapped the
chip since it's a clear user action.
