mod_http_muc_log: Fix redirect bug If you somehow went to /muc_log/room/yyyy-mm-dd/something it would send you in a redirect loop that continuously added path components until the path can't be parsed anymore. This should ensure that /muc_log/room/date/ is simply 404'd

module:hook("message/host", function (event)
	local stanza = event.stanza;
	if #stanza.tags == 1 and stanza.tags[1].attr.xmlns == "http://jabber.org/protocol/chatstates" then
		return true;
	end
end, -10);
