[FIX] sale_mrp: incorrect search of BOM in multicompany

In following configuration:
- We have two companies: A and B
- We have a shared product X
- We set a BOM of type KIT for this product X for company B only (the field company on a BOM is mandatory)
- We set no BOM for product X for company A because in company A we sell the product as a regular product

When we sell product X in company A, as a normal stockable product, the invoicing behavior is the same as
when we would sell KIT products. This is because we don't check the SO company when searching the associated
BOM.
