`com.route4me.sdk.services.routing.Route` does not contain several properties listed in [the spec](https://github.com/route4me/route4me-json-schemas/blob/598eb2847d39e3e2887f32d2183a1f181fdbc7d7/Route.json) like `member_first_name` and `member_last_name`. Also, `driver_alias` is null even though I've assigned a user to the route. I'm wondering what this property is supposed to do
