[6.1] voucher journal entry not based on correct rate

[Frederic Clementi - Camptocamp]

Hello,
test done under 6.1

I noticed that voucher journal entry not based on correct rate. Rate used is today 's rate instead of payment date (=voucher date) rate.

As we work with our scenario tool OpenERP Scenario (bzr+ssh://bazaar.launchpad.net/~c2c-oerpscenario/oerpscenario/6.1-main-focus/), I copied paste our scenario here in order to explain what this test does exactly :

Thank you

Frederic @ Camptocamp

@addons @account_voucher @2 @201

Feature: In order to validate multicurrency account_voucher behaviour. I create a customer invoice for 1000 USD (rate : 1.5) and pay 500 EUR (rate : 1). I import this invoice in a bank statement (module account_voucher is installed). The Journal entries must not calculate any currency gain/loss nor any write off. After the payment, my invoice should remains open.
