mod_report_forward: Fix traceback on error message passed to datetime function If archive:get() returns an error, e.g. because it can't find a message with the given ID, it may return e.g. nil, "item-not-found" or similar where the error condition ends up in reported_message_time, which gets passed to util.datetime, which thus ends up doing math to a string or error object.

module:hook("smacks-ack-delayed", function (event)
	if event.origin.type == "s2sin" or event.origin.type == "s2sout" then
		event.origin:close("connection-timeout");
		return true;
	end
end);
