[FIX] account: tax line amount
[FIX] account: tax line amount

The company currency is USD, the invoice currency is EUR.
- Create an invoice in EUR, set an invoice date
- Compute the taxes (click on "update" button)
- Change the exchange rate between EUR and USD
- Validate the invoice

At validation, the tax amounts are not recomputed. Therefore, they are
still converted in the company currency using the old rate.
