Some activities which are using old locations services (GeocodingWidgetActivity and GeocodingServiceActivity) are crashing when calling FusedLocationProviderService.requestLocationUpdates or FusedLocationProviderService.getLastLocation methods.

Use new LocationEngine abstraction to fix those crashes.
