Fix  T83122: NURBS Extruding multiple points only moves existing points

The Surface -> Nurbs Curve behaves now like the Curve -> Nurbs Curve,
if you initially select less than all points. So, multiple points can
be selected and extruded which just moves the selected points similar
to Curve -> Nurbs Curve object.
