title: rxjs/Subscription has no exported member 'Subscription'
body: <p>I updated my angular project and all my dependencies to latest version. Without to much trouble I solved most of the dependency issues, but I'm still stuck on RxJS. Here is my package.json: </p>

  </code></pre>
  
  <p>I'm only importing two modules from RxJS: </p>
  
  <pre><code>import { fromPromise } from 'rxjs/observable/fromPromise';
  import { Subscription } from 'rxjs/Subscription';
  </code></pre>
  
  <p>They are both giving the same error:</p>
  
  <pre><code>    [ts] Module '"***/node_modules/rxjs/Subscription"' has no exported
   member 'Subscription'.
  </code></pre>
  
  <p>It's exactly the same for <code>fromPromise</code>. Here is the error message I'm getting from <code>Subscribtion.d.ts</code> (I have not modified the code in any way)</p>

  <p>UPDATE:</p>
  
  <p>The answers bellow solved the issue with Subscription but <code>fromPromise</code> still gives the same issue even though it's exported correctly: </p>
  
  <p><code>export * from 'rxjs-compat/observable/fromPromise';</code></p>
