Fixed enableHighAccuracy: false on iOS

> enableHighAccuracy: false doesn't work on iOS
> ---------------------------------------------
>
> Key: CB-8523
> URL: https://issues.apache.org/jira/browse/CB-8523
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin Geolocation
> Reporter: Krisztián Schäffer
>
> According to my tests and to what I see in the source the GPS is almost
> always used even when enableHighAccuracy is set to false.
> The w3 spec says ( http://dev.w3.org/geo/api/spec-source.html#high-accuracy )
> about enableHighAccuracy that:
> "The intended purpose of this attribute is to allow applications to inform
> the implementation that they do not require high accuracy geolocation fixes
> and, therefore, the implementation can avoid using geolocation providers that
> consume a significant amount of power (e.g. GPS)."
> But the plugin uses kCLLocationAccuracyNearestTenMeters which is not a good
> choice for implementing that. There is hardly a low-power (non-GPS) method
> available which can provide 10 meters accuracy.
> The TODO comment also says that this is "arbitrary":
> https://github.com/apache/cordova-plugin-geolocation/blob/master/src/ios/CDVLocation.m#L156
> I suggest using kCLLocationAccuracyThreeKilometers. Any other constant will
> lead to GPS usage in rural environments when the wifi is off.
