Add disabled tests to CircleCI config

Summary:
These tests have not run for one reason or another since the migration from Travis. They are not passing, and are commented out to avoid flagging new PRs as breaking. These tests need to be fixed and re-enabled ASAP.
Closes https://github.com/facebook/react-native/pull/17959
