    transfer: add IdeTransfer::has_completed() vfunc
    
    This allows a check by transfer implementations to override whether or not
    they have completed. This might be useful for transfers that can be
    replayed due to something changing behind the scenes. (Such as a flatpak
    app/runtime installation).
