title: Lint warning "get is deprecated" when trying to manually inject NgControl
body: <p>Simple case but could not figure out the answer so far.<br>
  From angular v4 when trying to manually inject <code>NgControl</code>:</p>
  
  <pre><code>this.injector.get(NgControl);
  </code></pre>
  
  <p>The lint starts complaining:</p>
  
  <pre><code>get is deprecated: from v4.0.0 use Type&lt;T&gt; or InjectionToken&lt;T&gt;
  </code></pre>
  
  <p>How to properly inject it using <strong>injector</strong>?</p>
