[FIX] web: grouped list with <groupby> node and onchange

Let's assume an editable grouped list view with a <groupby>
node containing subfields, and an onchange. Edit a row to trigger
the onchange. Before this rev., it crashed because the onchange
specs was incorrect: it followed the relation of the many2one
and thus included its subfields (whereas it should only follow the
relation for x2many fields).

For example, go to Accounting > Accounting > Sales and edit the
label of a move line.
