[TIMOB-11831] iOS: GPS icon not turning off when app enters background

*Problem description* In kitchen sink, when you run Geolocation and hit the home button, the GPS icon will not turn off. All location listeners have been removed and Xcode Instruments confirms the GPS is turned off and there is no battery drain, yet the icon still appears as if it were turned on. Force closing the app or restarting the phone doesn't make it go away. Only disabling location services, or uninstalling the app makes the icon disappear. *Workaround* I have been able to fix the issue by editing Geolocation.mm, and adding [locationManager setDelegate: nil] before RELEASE_TO_NIL_AUTORELEASE(locationManager) in shutdownLocationManager() *Notes* - This issue can only be replicated on IPhone 4/4S running 5.1 or 6.0 - Cannot be replicated on Android, iPad, or the iOS 5.1/6.0 Simulator To be safe, I also created a VM with a clean install of MacOSX Lion, Xcode 4.2.1 and Titanium 2.0.0 and I was still able to replicate the issue. This was to discard the possibility of it being a corruption issue, bad install, or a recent framework/Xcode change. *Test case*

var mapView = Titanium.Map.createView({
	mapType : Titanium.Map.STANDARD_TYPE,
	animate : true,
	regionFit : true,
	userLocation : true,
	annotations : []
});
var win = Ti.UI.createWindow();
win.add(mapView);
win.open();
