title: Route Paramater causes wrong app root url
body: <p>In app.routing.ts I have added a route with parameters</p>
  
  <pre><code>  {
      path: 'manager-branch/:id',
      loadChildren: './components/manager/manager-branch/manager-branch.module#ManagerBranchModule'
    }
  </code></pre>
  
  <p>Everything works fine If I browse to it through the application, however if I refresh page while being on that component, my application root url will be wrong and page will fail to load. </p>
  
  <p>For instance, my application root url is <a href="http://localhost:4200" rel="nofollow noreferrer">http://localhost:4200</a></p>
  
  <p>If I refresh my page while being on any other component which doesn't have routing parameter, it will work fine.</p>
  
  <p>If I refresh my page while on <a href="http://localhost:4200/manager-branch/1" rel="nofollow noreferrer">http://localhost:4200/manager-branch/1</a> it will fail to load.</p>

    <p>Failed

    Found) <a href="http://localhost:4200/manager-branch/assets/css/font-awesome.min.css" rel="nofollow noreferrer">http://localhost:4200/manager-branch/assets/css/font-awesome.min.css</a></p>

  <p>You can see that app url is not correct. There shouldn't be manager-branch in it. </p>
  
  <p>Here's manager.branch.module.ts</p>
  
  <pre><code>@NgModule({
      imports: [
          ManagerBranchRoutingModule,
          CommonModule,
          Ng2BootstrapModule,
          ModalModule.forRoot(),
          FormsModule
      ],
      declarations: [
          ManagerBranchComponent,
          ManagerEmployeeComponent,
          EmployeeProfileComponent,
          ManagerTransactionsComponent,
          EmployeeTransactionsComponent,
      ]
  })
  export class ManagerBranchModule {}
  </code></pre>
  
  <p>The problem is in my app.module.ts</p>
  
  <pre><code>useClass: PathLocationStrategy
  </code></pre>
  
  <p>it works fine with HashLocationStrategy, but I have to stick with Path</p>
