    search-provider: Workaround for crashes in gweather_location_serialize
    
    gweather_location_serialize is currenty not ready to serialize cities
    without children weather stations eg: Warangal
    
    Skip those until we either get better serialization handling of those
    in libgweather or we change how we produce the data for the search
    provider interface
