[FIX] mrp, sale_mrp: set bom_line_id on all moves for kits

Current behavior:
When using 2 steps delivery and selling a kit product, not all
moves had bom_line_id set. So if you go in the transfers you
couldn't always see the "Kit" column in the operations.

Steps to reproduce:
- Activate 2 steps delivery
- Create a Kit with 2 products
- Create a quotation with kit and confirm it
- Go in the delivery
- In WH/Pick you can't see Kit column
- In WH/Out you can see the Kit column
