Handle exception during system initiated service transitions.

Media FGS related apis are expected to be called by media service(i.e
system_server) and are internal. Any exception will result in
system_server crash and soft restart.

There are legit scenarios when foreground transisiton may result
in exception.
Example:Some apps might be doing media playback without calling
startForegroundService.
