Re: [fetch] Aborting a fetch (#27)

My example was greatly simplified, it's more likely to look something like this:

```js
inputElement.onkeyup = function(){
  search.autocomplete(this.value).then(updateAutocompleteListWithResult);
}
let search = {
  active: null,
  autocomplete: function(string){
    if(this.active) this.active.cancel();
    this.active = fetch(`/autocomplete?q=${string}`)
    .then(r => r.json())
    .then(r => (this.active = null, r), e => (this.active = null, e));
    return this.active;
  }
}
```

In this scenario I'm not interested in the result of the autocomplete fetch if a new key up event occurs before the results are ready. In this scenario I'm not interested in neither the resolved nor the rejected value from autocomplete; I don't want `updateAutocompleteListWithResult` to be called with anything.
