Unhandled rejection click evaluatePage global code error

I installed node-horseman and i downloaded phantomjs and set it to environment variable (windows 7 64bit) when I tried to execute

var Horseman = require('node-horseman');
var horseman = new Horseman();
horseman
  .userAgent('Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0')
  .open('http://www.google.com')
  .type('input[name="q"]', 'github')
  .click('button:contains("Google Search")')
  .keyboardEvent('keypress', 16777221)
  .waitForSelector('div.g')
  .count('div.g')
  .log() // prints out the number of results
  .close();

I got the following error

I even tried using

var phantomjs = require('phantomjs');
var horseman = new Horseman({phantomPath: phantomjs.path});

The .click() is failing because the selector you tried to click does not exist.

Since different versions of PhantomJS throw slightly different errors, it would probably being easier (though kinda wasteful) to have horseman check is the selector is missing and throw an appropriate error @choxi. I would prefer catching the specific error of the selector not existsing, but I do not have the time lately to figure out how. I would be happy to accept a PR doing so though.
