Auto-queue requeues previously played stream

• [x] I checked, but didn't find any duplicates (open OR closed) of this issue in the repo.
• [x] I have read the contribution guidelines given at https://github.com/TeamNewPipe/NewPipe/blob/HEAD/.github/CONTRIBUTING.md.
• [x] This issue contains only one bug. I will open one issue for every bug report I want to file.

Steps to reproduce the bug

1. Enable Auto-queue next stream in Video and audio settings
2. Choose a niche video, e.g., https://www.youtube.com/watch?v=VFZNvj-HfBU
3. Let it play in the background

Actual behaviour

After a few other streams are enqueued, the original one gets enqueued again, leading to a very short loop of repeating videos.

Expected behavior

If previously played videos in this session are suggested again, they should be ignored and, say, the next one (and so on...) in the suggestion list enqueued instead

Device info

• Android version/Custom ROM version: LineageOS

Sorry, I just realised this is more a feature request than a bug...
