infinite-persistence ede83f358d Fix autoplay infinite loop
## Issue
Closes 3661: Autoplay + Related go into loops ( infinite ) sometimes

## GUI
Push the actual "next" item into the top of the list.

## History search
1. Skip if the next item is itself.
2. The URL stored in the history comes in various forms, so a direct comparison won't work.
  - There's also a weird case where the URL differs by just a little (p.09 vs p-09), but with the same claim ID:

lbry://vacuum-tube-computer-p.09-–-building#5212bc8bc63c373e2bf1ebc5b765595ed7b6514d
lbry://vacuum-tube-computer-p-09-–-building#5212bc8bc63c373e2bf1ebc5b765595ed7b6514d

Check the claim_id as well to cover cases like these.
