[FIX] mrp: create SM for by-products when RR triggered

When combining a reordering rule, the 3-steps manufacture and
by-products option, the picking from the post-production to the stock
will not contain the residual products produced by the MO (by-products)

To reproduce the error:
1. In Settings, enable:
    - By-Products
    - Multi-Step Routes
2. Inventory > Configuration > Warehouse Management > Warehouses, edit
company's warehouse:
    - Manufacture: 3 steps
3. Create 3 products P_compo, P_finished, P_secondary
    - P_compo is consumable
    - P_finished and P_secondary are storable
    - Routes of P_finished: Manufacture
4. Create a reordering rule for P_finished:
    - Min = Max = 1
5. Create a BoM:
    - Product: P_finished
    - Type: Manufacture
    - Components: 1 x P_compo
    - By-products: 1 x P_secondary
6. Inventory > Operations > Run Scheduler
7. Open the generated MO
8. Check Availability, Produce, Mark as Done
    - Note that in the "Produce" wizard, we mention that one P_secondary
is also produced
    - Also note that in "Finished Products" tab, there are 1 x
P_finished and 1 x P_secondary
9. Open the Transfers > Select the one from Post-Prod to Stock

Error: P_secondary is missing

When creating the byproducts move
https://github.com/odoo/odoo/blob/ad62f877c174d56b90ec516cf24494d751383db9/addons/mrp/models/mrp_production.py#L587
the field `move_dest_ids` is present (is the move created after
evaluating the RR)
https://github.com/odoo/odoo/blob/ad62f877c174d56b90ec516cf24494d751383db9/addons/mrp/models/mrp_production.py#L580
so it is used, but this will cause the `_push_apply` to skip the
evaluation of the move
https://github.com/odoo/odoo/blob/f0eaa756c4947e2a595359959b34b14bfda81a07/addons/stock/models/stock_move.py#L678-L679


and `_assign_picking` will not run, as it normally do when creating the
manufacture
