title: npm run not giving scripts as suggestion
body: <p>I had to setup my dev machine from scratch due to some issues and in doing so, I also upgraded from Ubuntu 14.04 to 16.04. </p>
  
  <p>I installed the latest node and npm, but I observe a strange behavior. When I press tab after typing the command </p>
  
  <pre><code> npm run sta
  </code></pre>
  
  <p>I am not getting any suggestions/autocomplete on the terminal. In the example above, I would expect it to autocomplete to </p>
  
  <pre><code>npm run start
  </code></pre>
  
  <p>I have defined many scripts within the package.json, but none of those show up as suggestions or autocomplete, on pressing tab. E.g. within my scripts I have defined, <code>pack-linux-x64, pack-darwin-x64</code> etc. but on typing </p>
  
  <pre><code>npm run pack
  </code></pre>
  
  <p>and pressing tab, I am not getting the suggestions from what I have defined within the scripts of my package.json. Strangely, I get </p>
  
  <pre><code>npm run package.json 
  </code></pre>
  
  <p>as the suggestion when I press tab. </p>
  
  <p>This, of course, was not the behavior in my previous system. </p>
  
  <p>If I type the command myself,e.g. <code>npm run pack-linux-x64</code> then it runs without any issues. </p>
  
  <p>How can I fix this?</p>
