iOS - Calling getPositionStream() method while location services are enabled and then disabling location services in Settings crashes the app

[Andrew-Tolentino]

🐛 Bug Report

Runner[3574:863495] LOCATION UPDATE FAILURE:Error reason: (null)Error description: The operation couldn’t be completed. (kCLErrorDomain error 1.)

Expected behavior

Reproduction steps

1. Call getPositionStream() while location services enabled on application
2. Go to Settings on the device and set: Allow Location Access - Never

The application then crashes.
When switching to previous versions before 6.0, the application does not crash.
When running the application on Xcode, I believe the error occurs on line 79 in he GeolocationHandler.m file.

@Andrew-Tolentino thank you very much for the clear bug report. You were 100% correct with the error being on line 79 in the GeolocationHandler.m file.

I have fixed the bug in PR #509 and will release a fix today!
