[Bug] When enabling use_pubsub_feeds, many videos get indexed multiple times

[krim404]

Describe the bug
After enabling use_pubsub_feeds, some videos are being indexed multiple times in the subscriptions tab. Invidious recognizes these as the same video, as evidenced by the following behavior:

• When one instance of the video is played, all duplicates are removed from the feed simultaneously.
• If the video is deleted from the watched list, all instances reappear in the feed.

This issue leads to redundant entries in the subscriptions feed, cluttering the interface.

Rollout is on a kubernetes cluster with a valid potoken and inv-sig-helper active.

Seems to happen with only one youtube channel. did you at one point tried to click multiple times on the same subscribe button for that channel?

just a bad example, had it on multiple different channels. i fixed it by truncating the video database and resync everything
