[FIX] mrp_subcontracting: multi-step receipt

- Activate the multi-step reception
- Create a Subcontracting BOM for product P and supplier S.
- Create a PO for S with P
- Validate the PO
- Validate the input transfer
- Validate the internal transfer

A error is raised because a mandatory field is not set.

The root cause comes from the INT move being flagged as a subcontract
move, while it shouldn't be. Indeed, only the input move should be
flagged as subcontract.

We force the `is_subcontract` value to `False` when a move is copied in
the context of a stock rule.
