Always call startForeground after startForegroundService

Browse source 
It's an error to e.g. stopSelf() without having called startForeground,
so do it even when about to exit.

// Notes on running under Oreo
//
// The goal is to be running only when useful: when user wants to play via
// BT. Ideally we'd not run the foreground service when BT is turned off, but
// there's no way to be notified of its being turned on without installing a
// receiver. So *something* has to be running, whether it's listening on a BT
// socket or hosting the receiver. Might as well be the socket listener. Users
// who want the service not running when BT's off can turn it off via app
// preferences. When they try to start a BT game we can note the preference
// and suggest they change it. And when an invitation sent is not received the
// sender can be told to suggest to his opponent to turn on the preference.
//
// When there's no BT adapter at all (Emulator case) there's no point in
// starting the service. Let's catch that early.
//
// Note also that we need to be careful to NEVER call stopSelf() after calling
// startForegroundService() until AFTER calling startForeground(). Doing so
// will cause a crash.
