mod_restrict_xmpp: Treat archive query as a read despite using iq-set
XEP-0313 uses iq-set to initiate a query, but unlike many other uses of
iq-set, this does not mutate anything on the server, so it should not be
treated as a write request.

local omemo_namespace_prefix = "eu.siacs.conversations.axolotl."
module:hook("iq/bare/http://jabber.org/protocol/pubsub:pubsub", function (event)

local node = stanza.tags[1].tags[1].attr.node;

origin.send(st.error_reply(stanza, "cancel", "item-not-found", "OMEMO is disabled"));
