[FIX] stock_landed_costs: multi-currency

- Activate 2 currencies
- Create a landed cost product
- Create a Vendor Bill in a currency different from the company currency
- Add the landed cost product
- Click on 'Create Landed Costs'

The landed cost is created in the company currency, but with the amounts
in the vendor bill currency.

This happens because the currency conversion is missing.
