Fix "TypeError: Cannot read property 'slice' of undefined" when using setCookies API

[jihchi]

Version: chromeless@1.2.0

Example code:

const { Chromeless } = require('chromeless');

async function run() {
  const chromeless = new Chromeless();

  const result = await chromeless
    .goto('https://httpbin.org/cookies')
    .setCookies('name1', 'val2')
    .html();

  console.log(result);

  await chromeless.end();
}

run().catch(error => console.error(error) || process.exit(1));

Result:

TypeError: Cannot read property 'slice' of undefined

We still want to keep the url part of this: https://chromedevtools.github.io/devtools-protocol/tot/Network/#method-setCookie as it's required (and consumers, right now, likely aren't adding it).

I think the solution lies in gracefully handling cookie.domain in the getUrlFromCookie helper

Hi @joelgriffith ,

Thanks for review PR.

I think the solution lies in gracefully handling cookie.domain in the getUrlFromCookie helper

cookie.domain is optional, do we need to handle undefined domain?

For setCookies(name: string, value: string) case, It do handling url, so for this case, this operation meet the requirement.

For other cases (such as setCookies(cookie: Cookie) and setCookies(cookies: Cookie[]), these API let consumer to provide url or domain which are optional.

I'm thinking about to handle url for Cookie type internally, complement cookie.url if no provided.
