[FIX] account,point_of_sale: increment customer supplier rank to commercial partner

Before this commit, if a customer/supplier has an invoice address, when
creating an invoice/bill it's the invoice address that will be
identified as the customer/supplier and that will have its rank
increased and not the commercial partner.

Now, the rank increment is done to the commercial partner as well.
