This does pass:

it(`Shows the correct WAC-Allow header on Alice's public folder`, async () => {
    const result = await solidLogicBob.fetch(`https://server/public/`);
    expect(result.headers.get('WAC-Allow')).toEqual('user="read",public="read"');
});

I'm not sure I got the process right for offering a PR on top of a request to review a PR - please let me know if there was a better way to do this.

Merged your PR into mine, if you approve this one, then i will merge it.
