core: fix cookie parsing (part 2) (#8150)

* core: fix cookie parsing (part 2)

After fixing cookie storage in #8133 I noticed that I still have a lot of '.json.bak' files in the Jackett configuration folder. After deleting them they were created again in each request. The cause was we were parsing bad the cookies with '=' character in the value. Most Cloudflare cookies include if so we were sending bad cookies and solving the callenge in each request.

This PR should increase performance in several ways: we are not solving the challenge again (it takes time), we are not making extra requests and we are not updating the Jackett configuration in each request (both files '.json' and '.json.bak').

Tested with the client HttpWebClient2NetCore only. Please do some tests with the site 1337x.
