storage.channel stop request has invalid URL

[AVVS]

channel id is used to construct request URI, and always results in 404 (gsutil has the same bug btw),

ie it should be: https://www.googleapis.com/storage/v1/channels/stop instead of https://www.googleapis.com/storage/v1/channels/channel-name/stop

this can be temporarily fixed with (since there is only 1 method for .channel, which is .stop - there are no checks on the interceptor

channel.interceptors.push({
  request: (requestOptions) => {
    requestOptions.uri = requestOptions.uri.replace(`${channel}/`, '');
    return requestOptions;
  },
});

Thanks for reporting! Sent a fix in #1146 -- feel free to try it out to make sure it works as intended.
