[BUG] stock_account_product_run_fifo_hook: raise error when validate the delivery order

[AungKoKoLin1997]

I am creating a migration PR at #1676. The CI tests failed due to an issue with stock_account_product_run_fifo_hook, and I suspect this module may not be functioning correctly. I tried testing it in the Runboat environment on the 16.0 branch, and I encountered the issue.

Steps to reproduce:

• Create a product with lot tracking, set its category costing method to FIFO, and enable automated inventory valuation.
• Create a purchase order for this product with a quantity of 5 and receive it with a new lot.
• Create a sales order for this product with a quantity of 5 and deliver it using the created lot.

After these steps, I encountered the issue shown in the attached image.
I believe the problem may be related to the following proposed commit: c913644

@AungKoKoLin1997 Too bad. I will check. It is not easy to solve, and it seems the core function it refers has been changed also.
