mod_pubsub: Fix traceback in disco of non-existent node (thanks Martin) In this case `ret` is a table not containing the node, which makes pubsub_error_reply() try to get an error template with that `ret` table as index, which returns a `nil` then passed to table.unpack, which in turn throws the error.

local xpcall = xpcall;

if select(2, xpcall(function (x) return x end, function () end,  "test")) ~= "test" then
	xpcall = require"util.compat".xpcall;
end

return {
	xpcall = xpcall;
};
