The test "has links" in app/src/components/navMenu/navMenu.test.tsx passes but it shouldn't. The divisions expectation still has DC_URL in the test. It only passes because the APP_ENV env var is set to "development" by default, so then DC_URL is an empty string. Update the test and we should think of a test environment set of env var values.

Same situation in app/src/components/navMenu/mobileNavMenu.test.tsx.
