[FIX] web: fix focus issue in fields x2many

Before this fix, when the user dared press 'TAB', the move_next event
was propagated from the sub one2many to the outer form renderer, and
caused the form view to try to focus another totally unrelated field.
Also, the event was sent twice, because we are in a case where a field
widget is contained in another field widget.
