            Tests the behavior of the `create` override in the model `mrp.production`
            regarding the values for the fields `move_finished_ids` and `move_byproduct_ids`.
            The behavior is a bit tricky, because the moves included in `move_byproduct_ids`
            are included in the `move_finished_ids`. `move_byproduct_ids` is a subset of `move_finished_ids`.

            So, when creating a manufacturing order, whether:
            - Only `move_finished_ids` is passed, containing both the finished product and the by-products of the BOM,
            - Only `move_byproduct_ids` is passed, only containing the by-products of the BOM,
            - Both `move_finished_ids` and `move_byproduct_ids` are passed,
              holding the product finished and the byproducts respectively
            At the end, in the created manufacturing order
            `move_finished_ids` must contain both the finished product, and the by-products,
            `move_byproduct_ids` must contain only the by-products.

            Besides, the code shouldn't raise an error
            because only one of the two `move_finished_ids`, `move_byproduct_ids` is provided.

            In addition, the test voluntary sets a different produced quantity
            for the finished product and the by-products moves than defined in the BOM
            as it's the point to manually pass the `move_finished_ids` and `move_byproduct_ids`
