Fix two bugs with Location when not using ACCESS_FINE_LOCATION (#10291)

Summary:
Fix two bugs with Location when not using ACCESS_FINE_LOCATION:
- If we request highAccuracy=false, because we don't have ACCESS_FINE_LOCATION, but we don't have access to the NETWORK_PROVIDER...then the code should not trigger a SecurityException because it fell-back to using GPS_PROVIDER (which we don't have permission for)
- If the device is pre-lollipop, and doesn't have a provider, we should detect this properly instead of letting the pre-lollipop code raise a SecurityException.

Unfortunately, SecurityExceptions cannot be caught by the calling JS code. But I am not fixing that one here, instead choosing to fix/obviate the SecurityExceptions altogether.
