[rename] out of sync still happens

#174

1. rename var1 (to shorter name)
2. rename var2
3. bug: breaks code

Tried to play around, but cannot repro

@customElement({ name: 'custom-element', template })
export class CustomElementCustomElement {
  @bindable foo: string = '';
  @bindable bar;


  hello(arg?: any) {}

  qux;


  thisisnothing;
  okaynext;


  useFoo() {
    this.foo;

    this.qux

    this.hello(this.thisisnothing);
    this.thisisnothing; this.okaynext;
  }
}

Another angle:

1. do some editing
2. dont save
3. rename
4. broken code
