[FIX] account_edi_ubl_cii : Fix constraints

Problem
---------
Because of this PR: 155896, the customer default value for the UBL
export values has been modified from commercial partner to partner.

However, in 16.0, some constraints have been added to verify that some
fields were properly set up before generating the XML. Those
restrictions clash with the said changes.

Indeed:
1 - Create NO company
2 - Set up UBL on invoice journal
3 - Create a new NO customer and set up UBL in the same way
4 - Create an invoicing address for that customer
5 - Create an invoice for with the customer set as the invoice address
set up in step 3.
6 - Send & Print with UBL selected

>> An error is added to the export errors while it should not.

Solution
---------
Use the commercial partner when checking constrains of all fields other
than addresses.
