[IMP] payment_authorize: display the reason for declining the payment

In some occasions, Authorize would decline a payment and provide the
reason for it, but not mark the payment as in error. The customer would
see that their payment is cancelled but not know what to do. That is
because error messages were not processed in the case of declined
payments.

This commit makes eventual error messages (decline reasons) logged on
the linked document's chatter and displayed on the /payment/status page.
