title: Angular 2 loadChildren not working with canActivateChild
body: <p>I'm trying to use Angular2 to lazy load some modules. I could make it work, but when I use it with canActivateChild, it blocks the navigation but load the module, I don't know if I need to do anything else, but I'd like to load the module only if I'm enable to access the route. For example, this is an admin dashboard and I want to load the AdminModule only when the user is logged.</p>
  
  <p>This is my main module routing:</p>
  
  <pre><code>export const routing = [
      { path: '', redirectTo: 'home', pathMatch: 'full' },
      { path: 'login', component: LoginComponent },
      {
          path: '',
          canActivateChild: [AuthGuard],
          children: [
              { path: 'home', component: HomeComponent },
              { path: 'adm', loadChildren: './admin/admin.module#AdminModule' },
          ]
      },
      { path: '**', component: NotFoundComponent },
  ];
  </code></pre>
  
  <p>And this is my admin routing:</p>
  
  <pre><code>export const adminRouting = [
      { path: '',
          children: [
              { path: 'client', component: ClientComponent },
              { path: 'support', component: SupportComponent },
              // more routes
          ]
      },
  ];
  </code></pre>
  
  <p>Like I said, everything in the navigation is working as expect, but when I'm not logged I wanted to prevent the lazyLoad module to be loaded.</p>
