Loading default chrome profile with webdriver does not automate browser

In the following topic: Load Default chrome profile with Webdriverjs Selenium, the solution listed there works fine but nothing happens when the browser is loaded, it's not loading the webpage. Here is the code:

var webdriver = require('selenium-webdriver'),
  chrome = require('selenium-webdriver/chrome'),
    assert = require('assert'),
    By = webdriver.By,
    until = webdriver.until;

var o = new chrome.Options();
o.addArguments("user-data-dir=/Users/rup/Library/Application Support/Google/Chrome/");
var driver = new webdriver.Builder().withCapabilities(webdriver.Capabilities.chrome()).setChromeOptions(o).build();

driver.get('http://www.facebook.com');

driver.wait(function() {
 return driver.getTitle().then(function(title) {
   console.log("title: " + title);
   return true;
 });
}, 5000);

I have the feeling it's because the "Chrome browser automation" extension isn't being loaded with that profile. I am new to webdriver so not sure how to include it, and if that would even solve the problem. i am using Webdriver JS (javascript).
