Set torch to off onDestroy(), fixes #2
Merge pull request #3 from BMc08GT/fixautoOnregression

Service: fix Auto On after quick re-launch

Fixes #2. In the off case the application is restarted too quickly, it hasn't destroyed the surface yet. Setting torch to off onDestroy() allows mIsTorchOn to return false when starting back up, thus allowing Auto On to turn it back on, instead of turning it off.
