Userinfo is ignored after a redirect to same origin

[lpinca]

Describe the bug

• Node.js version: v14.5.0
• OS & version: macOS 10.15.5

The Authorization header is not sent after a redirect to same origin if the initial request uses a URL with the userinfo subcomponent. It seems this stopped working with got@10.

Refs: MONEI/Shopify-api-node#390

Actual behavior

The Authorization header is not sent.

Expected behavior

The Authorization header is sent.

Code to reproduce

const assert = require('assert');
const got = require('got');
const http = require('http');

const server = http.createServer(function (request, response) {
  if (request.url === '/redirect') {
    assert.strictEqual(request.headers.authorization, 'Basic Zm9vOmJhcg==');
    response.statusCode = 303;
    response.setHeader('location', 'http://localhost:8080/');
    response.end();
    return;
  }

  assert.strictEqual(request.headers.authorization, 'Basic Zm9vOmJhcg==');
  response.end();
});

server.listen(8080, async function () {
  await got('http://foo:bar@localhost:8080/redirect');
});
