Subject: Fix dialer monkey NPEs

Monkey tests exposed a bug in Dialer where certain call shortcuts
could show up if contacts permissions were disabled and the UI was
changing quickly.

Don't enable shortcuts by default, and make sure to correctly
disable all shortcuts in the case of missing permissions.

Bug: 22225052
