App crash with: java.lang.IllegalArgumentException: Receiver not registered: com.zxcpoiu.incallmanager.AppRTC.AppRTCBluetoothManager$BluetoothHeadsetBroadcastReceiver@21990f5

Saw this application crash within incallmanager.

Looking at the error it looks like a bluetooth device disappeared under us?

Start in AppRTCBluetoothManager.unregisterReceiver at line 396 and stop at line 285, then trace the lifecycle calls through InCallManagerModule.stop and onHostDestroy. Reproduce the activity-destruction path and verify that receiver cleanup no longer throws the reported IllegalArgumentException.
