[FIX] sale_stock, purchase_stock: use product name as stock.move name

Steps to reproduce the bug:
- Create a Kit product "Kit 1":
    - Add a BOM with a component “C1”
    - Add a sales description
- Create another kit product without a sales description "Kit 2":
    - Add a BOM with a component "C2"
- Make sure you have a qty of “C1” and "C2"
- Create a SO:
    - Add "Kit 1" and "Kit 2"
    - Add any other storable product
    - Confirm the SO
- Go to the delivery → validate it
- Print the delivery slip

Problem:
The report doesn’t contain the kit product.

Because in the report, the `stock.move.line` are filtered by checking
the name of their move if it has the same name as the product in
the bill of material, but like the `stock.move` has the name
('description') of the `sale.order.line` instead of the product name,
the lines are filtered and not displayed:

The behavior is the same for purchase orders
