tree组件设置defaultExpandAll 异步获取值的情况下不会自动展开所有节点

[ZeroJsus]

• I have searched the issues of this repository and believe that this is not a duplicate.

Version

...0.5.1

Environment

...vue2.5.2

Reproduction link

example

Steps to reproduce

...1.设置a-tree标签
2.默认的treeNodes值设置为空数组
3.在mounted组件加载的时候给treeNodes的值赋值

What is expected?

... 应该是只有第一次获取值不是空的才能正确展开全部节点

defaultExpandAll 仅在组件第一次渲染时有效，不仅仅tree组件，其它组件的defaultXXX值都是这个行为，
可以自行搜索受控组件/非受控组件的概念。
如果你想异步获取数据后展开全部结点，可以使用非受控方式，或这种方式

谢谢你 你给的例子完美的解决了我的问题
