[FIX] account, stock_account: clean anglo-saxon lines

- Configure a Product Category Automated + FIFO
- Create a product in this category
- Create a PO for 10 units, receive the units, bill the PO and pay
- Sell 1 unit of the product and deliver it
- Create an invoice for the order
- Without paying the invoice, create a credit note with the option
  'Full refund and draft invoice'
- Post new invoice

The anglo-saxon lines are counted twice.

This happens because the lines already exist in the newly created draft
invoice.

For the sake of simplicity of the fix, we clean-up the invoice after
creation.
