[FIX] payment_authorize: confirm refunded validation transactions

As validation transactions are authorized rather than captured, they are
refunded with a void request. Before this commit, a voided validation
transaction was mistakenly flagged as canceled while it should have been
confirmed.

This commit makes the distinction between a voided regular transaction
and a validation transaction.
