Navigation and nested page-router-outlet with lazy loaded children

从链接的 ns-login-tab-navigation-ng13 示例开始，调整其嵌套的 page-router-outlet 设置，使球员和球队详情能够延迟加载。在跟踪路由器事件的同时，比较 @nativescript/angular 13.0.1 和 13.0.2 之间的行为；完成的标准是：在各个标签页之间反复导航到详情再返回仍能正常工作。

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 8.1.5
• Cross-platform modules: 8.1.5
• Android Runtime: 8.1.0
• iOS Runtime: 8.1.1
• Plugin(s): "@nativescript-community/ui-material-bottom-navigation": "~6.2.13"
• NativeScript-Angular: 13.0.2
• Angular: 13.1.1

Describe the bug

Navigation for a page-router-outlet is not working anymore after navigating back from details view.

I have a navigation setup with nested page-router-outlets, much like this example, except the children (player details and team details) are also lazy loaded modules with their own routes.

After starting the app, and the tabs are loaded with their lazy loaded module, I can navigate to the details view and back. However, when I try to navigate to the details view again, there's no response. I have enabled tracing on the router, and there are no events fired when navigating back. Also no events are fired on new navigation attempts.

If I navigate to another tab, I can repeat the process. Then that will be "stuck" as well.

To Reproduce
Use the example from the link above and lazy load the details components.

Expected behavior
Navigation should keep working regardless of lazy loaded children.

Additional context

This was working in @nativescript/angular 13.0.1, but then with issues like #49 and #53
