fix(ci): build latest chrome for e2e tests

This commit makes Travis download the latest chrome to run end to end
tests.  Previous tests bugged out as the webdriver became out of date
with Travis's bundled google-chrome installation.

This is also more technically correct from a testing standpoint since we
expect our users to be running the latest chrome browser.
