Motivation and Context

fix #257

Description

Desynchronize isLocationServicesEnabled

As comment, this change might cause some problems because of run in thread that location manager is not created in. Especially, around this line (change updating location status and accuracy) are suspecious. But I have no idea that critical situation that incorrect behavior that caller JS application cannot (or should not) handle.

If there are some problems about above, I will close this PR. If there are no problem, I will remove TODO comment before you marge.

Testing

I did simple operation confirmation with simulator.
