mod_rest: Do not allow replies to <iq type=result> from webhooks Replying to a result stanza could cause loops, just as replying to an error. No stanza.name check here but it should be fine since no other kinds of stanzas have type=result, and the boolean logic would most definitely be wrong on the first attempt.
