[CouchDB] Name or password is incorrect.

[zmaximo1990]

Describe the bug
After upgrade to the version 1.4.18 my connection to couchdb is broken.

To Reproduce
Steps to reproduce the behavior:

Run this script:

const ueberdb = require("ueberdb2");

const db = new ueberdb.Database("couch", {
  user: "username",
  password: "pass",
  host: "localhost",
  port: 5984,
  database: "dbname",
});

async function example(db) {
  await db.init();

  // no need for await because it's already in cache.
  db.set("valueA", { a: 1, b: 2 });

  db.get("valueA", function (err, value) {
    console.log("VALUE", value);
    // close the database connection.
    db.close(function () {
      process.exit(0);
    });
  });
}

example(db);

OUTPUT:

After inspecting databases/couch_db.js file, the config.auth values are incorrect.

Current values:

const config = {
      url: `http://${settings.host}:${settings.port}`,
      requestDefaults: {
        pool: {
          maxSockets: settings.maxListeners || 1,
        },
        auth: {
          user: settings.user,
          pass: settings.password,
        },
      },
    };

After change auth properties from user and pass to username and password the connection was successfully.

const config = {
      url: `http://${settings.host}:${settings.port}`,
      requestDefaults: {
        pool: {
          maxSockets: settings.maxListeners || 1,
        },
        auth: {
          username: settings.user,
          password: settings.password,
        },
      },
    };

PLEASE 🙏🏻 could you check that? Or what am I doing wrong?
