[FIX] product: Pricelist based on supplier prices (2)
[FIX] product: Pricelist based on supplier prices (2)

You can base both supplier and customer pricelists on supplier info
prices. For supplier pricelists, the existing patch introduced in
https://github.com/OCA/OCB/pull/165 is perfectly valid.

But for customer pricelists, this patch prevents the use of
variable standard price based on the supplier info records. This
patch covers both possibilities.
