[FIX] stock_account: value extra move MTO

- Create 2 products A & B in MTO, B with 'Buy' route + supplier
- Create a BOM for A: 1 Unit of B
- Create a MO for 1 Unit of A
- In the PO created, change the quantity from 1 to 2, receive the
  products
- In the MO, produce the unit and use 2 units of B

The extra move of B is not valued.

This is because the list of move to value is created before calling
`super()`. Indeed, the extra move is created in `super()`, and
moreover since this extra move is MTS (not MTO), the move line is
properly linked to the right move (unlike in #39121).

We add the extra move to the list of moves to value.
