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.

local disable_tls_ports = module:get_option_set("disable_tls_ports", {});

module:hook("stream-features", function (event)
	if disable_tls_ports:contains(event.origin.conn:serverport()) then
		module:log("error", "Disabling TLS for client on port %d", event.origin.conn:serverport());
		event.origin.conn.starttls = false;
	end
end, 1000);
