title: Angular 6 ng lint combineLatest is deprecated
body: <p>I recently updated from Angular 5 to Angular 6.</p>
  <p>I'm getting this warning <code>combineLatest is deprecated: resultSelector no longer supported, pipe to map instead</code>. Rxjs is version 6.1.0, tslint is 5.10.0, Angular CLI is 6.0.0 and Typescript 2.7.2. I'm using it like this:</p>
  <pre class="lang-js prettyprint-override"><code>const a$ = combineLatest(
    this.aStore.select(b.getAuth),
    this.cStore.select(b.getUrl),
    (auth, url) =&gt; ({auth, url}),
  );
  </code></pre>
  <p>I've tried it also like this:</p>
  <pre class="lang-js prettyprint-override"><code>empty().pipe(
  combineLatest(...),
    ...
  )
  </code></pre>
  <p>But this gives me: <code>combineLatest is deprecated: Deprecated in favor of static combineLatest</code> and empty is also deprecated in favor of its static version.</p>
