JS Alert Tests Failing in TravisCI Only

[erik-whiting]

There are three tests in tests/test_other_pages.py which test the functionality of interacting with Alert elements (JS alerts, prompts, confirms) which are failing in TravisCI. They are test_javascript_alert, test_javascript_confirm, and test_javascript_prompt.

These tests pass locally, but something about TravisCI does not like what's happening. Please note, element functionality was recently refactored, however this functionality wasn't touched. Travis is throwing the following exception:

ERROR: test_javascript_alert (test_other_pages.TestOtherPages)

My guess is that there is a timing issue where the test case is not waiting long enough for the alert boxes to show up. I found a promising looking StackOverflow issue that we may be able to implement to get it working again:
[Check if any alert exists using selenium python](https://stackoverflow.com/questions/19003003/check-if-any-alert-exists-using-selenium-with-with python)

If you are able to figure it out, please remove the the @unittest.skip lines above the test cases.

It is not just Travis some update broke these tests. I just checkout to an old commit #39 and it works in my local computer, but with the up-to-date development branch, I get the "UnexpectedAlertPresentException" in my local computer, even if I add some big manual wait like time.sleep(5), and I can visually confirm that the alert appears by removing the "headless" option.

Should be fixed by #44
