Wrong refund of invoice with 5x payment term

- create a fresh database with the accountant module, the generic account chart and demo data
- create a payment term named (5x payment) with
    - 60% immediately
    - 10% after 30 days
    - 10% after 60 days
    - 10% after 90 days
    - 10% after 120 days
- create a customer invoice to Agrolait with 1 line of 1000€ using this payment term
- validate this invoice
- click on Refund invoice
- In the refund wizard, select: Cancel: create refund and reconcile.
- validate the wizard.

=> Result :

The invoice is not considered paid :

Subtotal 1000.00 €
Tax 150.00 €
Total 1150.00 €
Balance 460.00 €

Two account moves are created, one of them being a write-off.

The created account move lines are in the attached ods file, the writeof is inconsistent and the reconciliation is wrong.
