[whatwg/xhr] FormData's append method does not match browsers (#73)

https://xhr.spec.whatwg.org/#interface-formdata

> The append\(name, value, filename\) method, when invoked, must run these steps:​ 

See discussion in https://github.com/tmpvar/jsdom/issues/1533

Given this code:

```js
var formData = new FormData();
var file = new Blob([
   JSON.stringify({})
], { type: 'application/json' });
formData.append('somename', file);
formData.entries().next().value
```

My reading is that per the spec this should append a new entry whose name is "somename" and whose value is a Blob to the form data. Then, entries().next().value should return the Blob right back.

However, apparently in Chrome and Firefox it does not do that. Instead it converts it to a `File` (not a `Blob`) with, at least in Chrome, name "blob".
