fix: empty related videos when able to choose the topic of related videos

Fix empty related videos when the watch page contains autoplay feature

It happens in some regions or when using cookies.

closes #810
closes #848

info.nextVideo = info.related_videos[0] can close #848 too. But I think it's not neccesary.

hi, thanks for another PR

how did you generate the watch.html page with autoplay on? is that something that can be turned by a cookie or user setting? i'd like to add it to test/files/refresh.js in case it needs to be updated in the future

[skick1234]

Actually, this is not because the autoplay feature is on.

When I logged in, related videos can be sort (e.g. All, Cats, Recently Uploaded). This makes related videos empty.

My autoplay json file

I tried to remove all the account-login cookies (keep PREF, ... cookies) but I cannot reproduce that. Maybe this is a user-only feature or a beta feature, idk.

regular json file

EDIT: This is Up Next Topics feature I think

hmm, so the saved html and json pages can't be added to refresh.js since the new format won't be on there? are the json screenshots from requests in your browser?

I'm afraid that can't be done without an user cookie.

I logged from miniget response with my clone's cookie.

i still think related-topics should be added to refresh.js, only for future maintenance. just add a note that it needs a requestOptions: { headers: 'YOUR_COOKIE' }.

btw, the watch.html file contains possibly identifying values from the account you used, things like ID_TOKEN and INNERTUBE_API_TOKEN. i'm actually not sure how compromising these are, but could be worth removing them if you have concerns. or maybe you used a throwaway account and it doesn't matter

[skick1234]

I used my clone account to run refresh.js.

Maybe we should add a cookie to environment variables. Or just update it manually :>
