    osmUtils: Don't update a place's name if not in the OSM object
    
    When a place has been edited on OSM don't reset the Place's name attribute
    if it's not set in the OSM object, since the PlaceFormatter assumes this
    is set. For bare address nodes, this would be set to a value contructed
    from the address components, so we shouldn't remove this just because
    the OSM object doesn't have a name set.
    This fixes stack trace when saving places like that.
