Correct a bug in the UpdateSession::close() mechanism.

* Bug: In Hurricane, UpdateSession::close(), when re-materializing, the
    cells must be notified <CellChanged> *after* all the Gos are
    re-materializeds. In fact they must also revalided according to the
    deepness of their instanciation (the deepest first). Has still to
    be done.
