Original change's description:
> controlledframe: Update webrequest test
>
> Looking at CI, assertion of onErrorOccurred never gets checked because
> when error occurs, onComplete will fail the assertion in the previous
> block. In this CL we rearrange the order to observe onErrorOccurred
> error message.
>
> Also enforced URL filter rules so the API does not get triggered on
> unrelated requests.
