[IMP] product, purchase: vendor reference in multi-company

- Create 2 companies A & B
- On a product P, define 2 suppliers (same vendor), one for each
  company, but with a different Vendor Product Code
- Create a PO in A for P

Both supplier codes are proposed in the Many2one widget, while only the
code for A is expected.
