This reverts commit fcb6dc55. https://github.com/npm/npm/issues/16970 made the e2e in CI failed for changes containing the top level packages like https://github.com/facebookincubator/create-react-app/pull/3105 and https://github.com/facebookincubator/create-react-app/pull/3100.
I think we need to wait a little more to run npm 5++ in CI
