Don't use __eq__ it's broken in Selenium.

If you return a WebElement from a method then you get the following error:

Traceback (most recent call last):
...snip...
File "/Users/tirsen/triposo/devel/triposo3/venv/lib/python2.7/site-packages/holmium/core/pageobject.py", line 211, in wrap
  resp = attr(*args, **kwargs)
File "/Users/tirsen/triposo/devel/triposo3/iosguide/automator.py", line 43, in get_next_version_and_status
  return self.get_next_version_element().text.split(' ')
File "/Users/tirsen/triposo/devel/triposo3/venv/lib/python2.7/site-packages/holmium/core/pageobject.py", line 212, in wrap
  if None == resp:
File "/Users/tirsen/triposo/devel/triposo3/venv/lib/python2.7/site-packages/selenium/webdriver/remote/webelement.py", line 351, in __eq__
  if self._id == element.id:
AttributeError: 'NoneType' object has no attribute 'id'

This is because the Selenium WebElement class __eq__ method can't handle being called with None. (I don't think it's implemented correctly.)

It's much safer to check for None like this.

Coverage remained the same when pulling c079b04 on tirsen:master into 745bc0d on alisaifee:master.

@tirsen thanks. I changed a test case to reproduce the problem (4f2048c) - and indeed the test case fails without your patch when I run the test locally. However, for some reason its not failing on travis. Could you please also try out that test.

I can't really run the unit tests. I get the following error:

I've installed phantomjs. Do you have any instructions on how to set
everything up?

Hi @tirsen. For phantomjs to work all you need is for phantom to be on the PATH. check if which phantomjs returns a valid location. I personally installed it with homebrew.
