Previously published npm packages are being overwritten by the publish tool #339

The publish tool should not be overwriting previously published packages.
https://docs.npmjs.com/policies/unpublish
Overwriting published packages is against npm's policy, and I'm not sure how this was even possible because the npm registry should be immutable.

We are using @types/react-redux 7.1.16. That npm package was originally published 9 months ago, but overwritten 6 days ago.
https://www.npmjs.com/package/@types/react-redux/v/7.1.16

I started looking into some of the other packages that would have been affected by that same PR.
https://www.npmjs.com/package/@types/chai-enzyme/v/0.6.7
https://www.npmjs.com/package/@types/emoji-mart/v/3.0.4
https://www.npmjs.com/package/@types/enzyme/v/3.10.8

All Types (@types) packages affected by the above PR have their previously published npm packages overwritten 6 days ago.
