title: Navigate to root route "/"
body: <p>I am trying to navigate to home route from a child route but nothing happens.</p>
  
  <p>I.e. the current route is <code>/projects</code></p>
  
  <p>Neither <code>this.router.navigate(['/'])</code> nor <code>routerLink="/"</code> works.</p>
  
  <p>My <code>routerConfig</code> looks like this</p>
  
  <pre><code>const routes: Routes = [
   {
     path: '',
     component: HomeComponent
   },
   {
     path: '/projects',
     component: ProjectsComponent
   }
  ]
  </code></pre>
  
  <p>How do I go about doing this?</p>
