To reproduce the issue:
1. In Settings, enable "Multi Routes"
2. In Routes, unarchive MTO
3. Create a product P:
- Storable
- With a vendor
- Routes: MTO + Buy
4. Create and confirm a SO for 10 x P
5. On the delivery, set the done quantity to 12
6. Validate the delivery
Error: The state of the delivery is set to _done_ but the SM has
changed, its demand is 2 and the done quantity is 0. Moreover, a
backorder has been created
Since [1], extra moves are supposed to be merged with the initial
one. However, there is an issue with the above case. The initial SM
has generated a POL (the product is an MTO-buy one). However, since
the extra move is an MTS one, it does not generate any POL. As a
result, the SMs don't have the same value for the field
`created_purchase_line_ids`. This is an issue because for two SM to
be merged, this field must be the same on both SM:
https://github.com/odoo/odoo/blob/ef3c21255c6f2b1172be3b1f8f0dc83bc276d806/addons/purchase_stock/models/stock_move.py#L20-L24
As a result, the SMs are not merged, the method `_create_extra_move`
only returns the extra move, the initial one is lost and it leads to
an unexpected behaviour.
We should also copy the values of `created_purchase_line_ids` to
ensure the merged of both initial and extra moves.
