[FIX] use refund's date in write-off

Found in a client: if you use the refund wizard on an invoice with the 2nd or 3rd option, and there is a write-off due to the reconciliation of the invoice and the refund, the date is set to today instead of taking the refund's.
This can lead to some issues, since the period is however the one from the refund.
