Call to nearby roads API does not give same error about not having billing setup as the geocoding API does.

Steps to reproduce

1. Create a basic project requesting snap to roads
2. Use API key associated with project that does not have billing enabled.
3. Issue request

One will get an empty response but no error. The geocoding API does return an error stating that billing must be enabled.

Code example

c, err := maps.NewClient(maps.WithAPIKey(os.Getenv("GOOGLE_MAPS_API_KEY")))
	if err != nil {
		log.Fatalf("fatal error: %s", err)
	}

	r := maps.NearestRoadsRequest{Points: utils.GeoPointsToGmapLatLngs(geoPoints)}

	resp, err := c.NearestRoads(context.Background(), &r)
	if err != nil {
		log.Fatalf("fatal error: %s", err)
	}

	pretty.Println(resp.SnappedPoints)
