tough-cookie integration broken in Jest

• Node.js version: 13.9.0
• OS & version: Darwin 18.7.0

A got call with a tough-cookie CookieJar where the response has a set-cookie header rejects if run in Jest. The repro repo below contains both a yarn start script that runs in plain Node and succeeds, and a yarn test script that runs the same code in Jest.

#811 was closed in favor of jestjs/jest#4305, however it seems that, at least after the got refactor, util.promisify itself in Jest is not the problem - got's role in this appears to be the "Horrible tough-cookie check" - removing the following !Reflect.has conditional (making the two assignments unconditional) resolves the issue.

Jest's new role in this is very likely due to something like jestjs/jest#2549, but that is unlikely to be fixed in Jest anytime soon.

Actual behavior

Rejects with

    TypeError: cb is not a function

Expected behavior

Sets the cookie into the cookie jar with no error.
