nz-tree无法勾选异步传回的数据

[MrCodeFront]

Reproduction link

https://stackblitz.com/edit/ng-zorro-antd-start-tuctjh

Steps to reproduce

父子组件传值，点击子组件的搜索按钮，模仿异步获取到数据，子组件的数据更新了，指定的勾选数组也有了，但nz-tree无法将数据勾选上

What is expected?

点击搜索按钮后，数据改变的同时应该勾选指定数组的数据

What is actually happening?

点击搜索按钮后，数据改变了，但没有勾选指定数组的数据

Environment	Info
ng-zorro-antd	8.3.0
Browser	chrome version(77.0.3865.90)

我没使用官方提供的nzSearchValue实现搜索功能，而是使用自定义的搜索功能实现的实时的网络异步请求

Translation of this issue:

nz-tree can not check the asynchronous data returned

Reproduction link

Https://stackblitz.com/edit/ng-zorro-antd-start-tuctjh

Steps to reproduce

Sons components by value, click on the search button subcomponents, to imitate asynchronous data acquisition, data subcomponents updates, check the array has also been specified, but nz-tree can not check on the data

What is expected?

After clicking the Search button, the changed data at the same time should check the data specified array

What is actually happening?

Click on the search button, the data has changed, but did not check the data of the specified array

Environment	Info
Ng-zorro-antd	8.3.0
Browser	chrome version (77.0.3865.90) ​​

I did not use the official implementation nzSearchValue search function, but the use of real-time network asynchronous self-defined search function implemented request

同样的, 我想问下: 我的树节点数据从后台拉取, 可以正常显示, 但是回显已经选中的节点失败, 发现是异步问题惹的祸,

目前 nzCheckedKeys 等属性还不支持双向绑定

参考#4472
在异步后执行下面语句.
this.defaultCheckedKeys = [...this.defaultCheckedKeys];
