Function name shortened, but not function call

There seems to be a problem with shortening names in some cases. Below is an example.

```js
{
addOnclick: function(){
element.onclick = ()=>{this.foo("some string")};
},

foo: function(str){
//do things
}
}
```

I get: "this.foo is not a function"
What it looks like is happening is that it is changing the name of the function, but it is not changing the call to that function. It seems to do this everywhere that I have this format as far as I can tell. It works with browserify of course, but it breaks with tinyify.

从 issue 中的 JavaScript 示例开始，通过 tinyify 重现该示例，并将输出与 browserify 进行比较。跟踪名称缩短路径，并验证缩短后的函数名及其调用是否得到一致修改；完成的标准是该示例不再引发 "this.foo is not a function"。
