  test(ZNTA-1927): update tests, add enzyme

Updated tests. Was having issues trying to render a stateless component
since that is not well supported by the standard TestUtils. Used enzyme
in that test instead, which supports stateless components and has a
cleaner API anyway. We should use enzyme in all our tests.
