title: Revert version of unpublished Node.js package
body: <p>I have a package which I released on NPM and it's currently at version <code>1.0.1</code>.</p>
  
  <p>I have made some changes locally, and wanted to publish them.
  I entered <code>npm version 1.0.3</code> and then felt stupid, because I wanted to type <code>npm version 1.0.2</code>.</p>
  
  <p><em>How can I restore this mistake?</em>  </p>
