[FIX] web: prevent crash with invisible x2m and onchanges

When an invisible x2many field is modified by an onchange, we had a
crash because the reset function did not return a deferred in that case.

This happens because the signature of _render in AbstractField allow for
an undefined return value, but the reset method should return a
deferred.

This was an issue for example in stock: editing the
pack_operation_product_ids one2many field in a stock.picking could
trigger an onchange on another invisible one2many (with no inline views).
