title: How to reload the current route with the angular 2 router
body: <p>I am using angular 2 with <code>hashlocation</code> strategy.</p>
  <p>The component is loaded with that route:</p>
  <pre class="lang-js prettyprint-override"><code>&quot;departments/:id/employees&quot;
  </code></pre>
  <p>So far fine.</p>
  <p>After I do a successful batch save of multiple edited table rows I want to reload the current route URL via:</p>
  <pre class="lang-js prettyprint-override"><code>this.router.navigate([`departments/${this.id}/employees`]);
  </code></pre>
  <p>But nothing happens, why?</p>
