make tests work on circeci

[alpiazza13]

there's a circleci config variable:
CIRCLECI=true

try making the chromedrvier call just do driver=webdriver.chrome(options=options), in fetch_page.py

I switched to Github Actions for CI, but it's currently running only the parsing tests, not the browser automation tests. I'm not confident we can do Selenium browser automation with either CI system.
