[fix] SuperTest agents not sending cookies for Localhost domain cookies, you must set them to 127.0.0.1

I'm unable to have the agent to automatically send my cookies to my requests after a successful login. What I don't undersand is that if try to set the cookies manually reading them from the agent itself it just works, but if i just remove the .set("Cookie") it stops working immediately. In my node express application, the very first thing I do is to setup cookieParser. It seems similar to the provided example on agents and cookies. The cookies are set as insecure already. Does the httpOnly flag of the cookies affect to this?

const app: Express = express();
app.use(cookieParser());

const response: Response = await myAgent.post("/post")
   .field("description", "This is a test post.")
   .field("price", "100")
   .set(
     "Cookie",
     myAgent.jar.getCookies({
         domain: "localhost",
         path: "/",
         secure: false,
         script: false,
       })
       .at(0)!
       .toString()
   )
   .redirects(5);

It seems that it was due to using localhost as the domain for cookies, it should be 127.0.0.1 in order to make it to work. It was working with the browser, so I was wondering if the agents should support "localhost" as domain or not.

This issue is related to ladjs/superagent then or to supertest?
