Null Pointer Exception in HyperionService.forceDisconnect

[EmmettWilson]

Hyperion service can cause application crashes on some configuration changes if they happen before the service can be bound to an activity.

This looks like it can easily be fixed by null checking the service before unbinding in forceDisconnect

        void forceDisconnect(){
            // `onServiceDisconnected` doesn't seem to be called as expected, so this method guarantees unbinding.
           if(this.service != null){
               this.service.detach(activity);
           }
            service = null;
        }

I had the same issue here.
