NullPointer when destroying BeaconService

[Del-S]

Hello,

I'm testing new Pre-release (2.15.3-beta1) and I'm getting this NullPointerException when I'm destroying BeaconService.

java.lang.RuntimeException: Unable to stop service org.altbeacon.beacon.service.BeaconService@28ee2fe: java.lang.NullPointerException: Attempt to invoke virtual method 'void org.altbeacon.bluetooth.BluetoothCrashResolver.stop()' on a null object reference

Seems like BluetoothCrashResolver is created only for API under 21 but onDestroy does not check for this condition or if it exists.

This was just fixed in #790, although it has not yet been put into a release. It will be in 2.15.3
