The attribute Id has been updated, does the attribute nameId also need to be updated?

https://github.com/jashkenas/backbone/blob/0b1c2e3fce3156fcb9819b8bbf8885456e4e1055/backbone.js#L519

```
var hacker = new Backbone.Model({
name: "name",
idAttribute: 'nameId',
});
if (this.idAttribute in attrs) this.id = this.get(this.idAttribute);
```
The attribute Id has been updated, does the attribute nameId also need to be updated?
I don't think it is necessary to update the attribute id, just the nameId

Start by reading the referenced section of backbone.js around line 519 and trace how idAttribute and the model's id are assigned during model initialization. Compare that behavior with the issue's nameId example and existing model tests, if available; done means the expected relationship between the configured attribute and id is documented or covered by a test.
