Fix calls to dynamic routines in identification

The attached file contains a moving average process. It crashes identification in calls like

    [residual, g1 ] = feval([M_.fname,'_dynamic'],yy0, ...
                            repmat(oo_.exo_steady_state',[M_.maximum_exo_lag+M_.maximum_exo_lead+1]), M_.params, ...
                            oo_.dr.ys, 1);

Here, the period number (last argument) is always set to 1 instead of presumably M_.maximum_exo_lag+1 .
