Restore Dialer content after permissions granted

First pass at making Dialer display the call log, favorites,
all contacts, and contact search after permissions are granted
withut having to restart the app.

Update cached permission status in onResume for Dialer activities
Update SpeedDialFragment to correctly initialize loader in
onResume if it was null previously because of revoked permission.
