4.2.2 touched the NotificationManager service, and some logic went missing in the merge it seems.
This should take care of it.

Fix NavButton AlphaGlow when pressed

Note that since users can set the Navbar Alpha, this will be a relative
brightness. In AOSP the button brightens to 1f alpha when pressed (.7f is not pressed).
if user sets alpha to 1.0, then there will be no difference.
