Description

A simplified version of https://github.com/FreeTubeApp/FreeTube/pull/4340 that doesnt worry about having a lot of logic for fetching thumbnails if it's missing, the thumbnails can be fetched from other places (visiting the channel, refreshing subscriptions with local api + no rss)

Screenshots

Testing

See: https://github.com/FreeTubeApp/FreeTube/issues/3735#issuecomment-1642286050 & https://github.com/FreeTubeApp/FreeTube/pull/4340

Change file extension .txt to .db

(Notice how much faster importing subscriptions is)

Hi error~

[PikachuEXE]

Oops more errors

[ChunkyProgrammer]

@PikachuEXE found the issue, interestingly, this error could happen when not using this PR

[PikachuEXE]

Duplicate keys detected: 'UC59AcfHD5jOGqTxb-zAsahw'. This may cause an update error.

@PikachuEXE you're somehow subscribed to the same channel multiple times, not sure how that happened

I think the double subscribe issue should be fixed here: https://github.com/FreeTubeApp/FreeTube/pull/5617/commits/60a11d39290d9280f58a7636ec3eeb692142eb38 (you'll need to unsubscribe from the duplicate manually)
