Title: Catch WebDriver exceptions when creating selenium browser

Observed this exception twice in the cluster:

selenium.common.exceptions.WebDriverException: Message: u'chrome not reachable\n (Driver info: chromedriver=2.1,platform=Linux 3.2.0-40-virtual x86_64)'

I was able to reproduce locally in about 1/50 trials. This change appears to have resolved this issue (ran 200 trials successfully).
