[metacity] window: load NET_WM_USER_TIME from the right window

    window: load NET_WM_USER_TIME from the right window
    
    On subsequent changes, if there is a NET_WM_USER_TIME_WINDOW, then
    read the property from that rather than from the main window.
    (Fix an accidental regression: the right Window was being computed
    but no longer passed in.)
