Describe the bug
Getting this warning when building prod webpack config and running it

You are currently using minified code outside of NODE_ENV === 'production'. This means that you are
running a slower development build of Redux. You can use loose-envify
(https://github.com/zertosh/loose-envify) for browserify or DefinePlugin for webpack
(http://stackoverflow.com/questions/30030031) to ensure you have the correct code for your production build.

#534
I think this was already mentioned and resolved but is still happening

To Reproduce
Steps to reproduce the behavior:

clone https://github.com/raven619claw/starter-kit/tree/develop
run yarn
yarn build:prod and then start with yarn start:prod and you would see the warning

Expected behavior
Warning should not be there as NODE_ENV is correctly set
