SystemUI: Fix RemoteDisplayTile crash on clean boot

Previously a patch was put up to fix adding/removing tiles due to a race
condition and not checking with the executor was still active at the
time of onPrepare(), but we did not add the check to unPrepare(). This
bug only seems to surface on a clean boot.

Add the same check to unPrepare() to avoid crashing.

frameworks: fix setting default ringtone for multi sim

The defualt value for the ringtone expects a "_" between the setting and
the requested sim subscription. This was not being respected in the
mediascanner when it set the default ringtones, resulting in the setting
value being "ringtone2" instead of "ringtone_2".
