    history-service: make sure we can update pages' titles and urls
    
    When we retrieve a url from the backend from a user given
    EphyHistoryURL, it's possible for this to contain updated information
    for the page. In such case, don't overwrite this with the one stored
    in the backend.
    
    This makes possible to later update this information when saving a new
    visit.
