[FIX] stock_account: no analytic info on COGS

- Create a FIFO product, Automated
- Make some stock
- Create a SO, add the product
- On the SO, add an analytic account
- Validate the picking, create the invoice
  => the analytic info are propagated to the invoice, as expected
- Validate the invoice

The analytic info is propagated on the COGS entries, in particular the
the output account, which is incorrect.
