RangeError (index): Index out of range: no indices are valid: 0 on GeoJsonFeatureCollection.toJson if empty collection is returned from OpenRouteService

[miklcct]

GeoJsonFeatureCollection.toJson() does not work if the collection is empty from OpenRouteService.

import 'package:open_route_service/open_route_service.dart';

final openRouteService = OpenRouteService(apiKey: 'my_api_key');

void main() async {
  print((await openRouteService.geocodeAutoCompleteGet(text: 'skhfdkashfdkjashfdjs')).toJson());
}

Error:

Please review #22. Should fix this. Also contains Unit Tests to verify this and other empty cases.
