    network: Fix connection editor blanking when removing manual entry
    
    To delete a manual entry row (IP addresses or routes) the remove_row
    function started walking the widget hierarchy at the connection editor
    widget. This caused the entire dialog box getting removed. Begin at the
    GtkButton instead to actually remove the corresponding line.
    
    Fixes #972.
