Ghost version 0.20.0 hosted on NPM repository

Bug description:

A project I got to work on had the following issue #1849. As stated the fix is to update to >0.19.6.
Ours was listed as 0.20.0 in package.json so I assumed something else was the source of the bug.
Later when I noticed that our version was 0.20.0 and the latest release only goes up to 0.19.8 I found out that somehow there is a 0.20.0 version hosted on npm:
https://registry.npmjs.org/ui-select/-/ui-select-0.20.0.tgz
The date mentioned to the version number are from the release version 0.19.5 hence why we were still having this bug.

Still trying to figure out how we got to version 0.20.0 and why this is hosted on NPM and why it seems to be a duplicate of 0.19.5.

Link to minimally-working plunker that reproduces the issue:
