Re: [w3c/ServiceWorker] clarify behavior when fetch event handler throws (#896)

As long as it triggers a promise rejection, yes.

I guess we should clarify what this does:

```
void broken() {
  return new Promise((resolve, reject) => {
    setTimeout(_ => {
      throw new Error('boom');
      resolve();
    }, 0);
  });
}
evt.waitUntil(broken());
```

Here, the promise never resolves or rejects.  Eventually it will be killed by the browser for taking too long.  I think this should probably be treated as a rejection.  I'm not 100% sure what we do today.
