[FIX] account: invoices on unmatched payment

When unreconciling a payment from an invoice, the link between
the payment and the invoice (in many2many invoice_ids)was kept
and then the invoice still appeared when clicking on the button
invoices in the payment form view.

The invoice must be removed from invoice_ids.
