title: how do a click on a link in webdriverIO
body: <p>I am trying to click on a link in a web page with webdriverIO.
  I can navigate to google.com page and then I enter a search term.</p>
  
  <p>But when I try to click on a link containing the text I want, it doesn't click the link.</p>
  
  <p>What am I doing wrong:</p>
  
  <p>Here is my code:</p>
  
  <pre><code>var webdriverio = require('webdriverio');
  var options = {
      desiredCapabilities: {
          //browserName: 'phantomjs'
          browserName: 'chrome'
      }
  };
  webdriverio
      .remote(options)
      .init()
      .url('http://www.google.com')
      .setValue('*[name="q"]','webdriverio')
      .click('*[name="btnG"]')
      .pause(1000)
      .getTitle().then(function(title) {
          console.log('Title was: ' + title)
      })
      .getText('=webdriver.io').then(function(text) {
          console.log('Title was: ' + text); // outputs: "WebdriverIO"
      })
      .end(); 
  </code></pre>
  
  <p>I am running webdriverIO with node.js v6.9.2 and selenium stand alone server 3.0.1.</p>
  
  <p>Thanks.</p>
