* Fix incorrect check if CI variable is set to true

Originally build would fail on warnings with any value of CI environment variable. Now it will correctly check if it's true.

Discussed here: https://github.com/facebookincubator/create-react-app/issues/2453

* Check for "not false" instead of "not true"

After discussion we decided that this will be closer to current functionality and not break anything.

It should be `baz` instead of `bar` on last example.
