在子应用中使用路由时，浏览器后退需要点多次才可后退

[my5201314zwl]

Describe the bug 子项目中 const routes: Routes = [{ path: '', component: HelloComponent, children: [ { path: '', redirectTo: 'test1', pathMatch: 'full' }, { path: 'test1', component: Test1Component }, { path: 'test2', component: Test1Component } ] }];

在test1和test2间进行路由切换，此时浏览器后退按钮不好用。

微前端下使用 redirectTo 和 pathMatch: 'full' 有问题，

[
 {
   path: '', 
   redirectTo: 'test1', 
    pathMatch: 'full'
  },
]

升级到 15.1.1 版本，替换成 redirectToRoute 即可

[
 redirectToRoute('test1')
]
