[IMP] sale_stock: change 'date' on 'Sales Order Portal Content'

Currently on a Sales Order Portal view, the field 'date'
under the delivery order shows the creation date of deliveries
linked to the SO,
After this commit it should display the 'effective date'
(or'scheduled date' if not yet delivered) of deliveries linked to
the SO
