Input settings: fix empty screen when launching from keyboard

Fixes AOSPA-439

Change-Id: I70a61d82f9cddbc88b8fb803081336bb79a98fa1
Blacklist: Avoid crash when dialog dismissed via back button.

A user usually presses the back button only
when he/she does not want the changes to be saved.
Hence we need to revert the changes that took place
when the dialog is dismissed with back button.
