Closes 5000: AutoPlay in Floating Player only works one time
Factor out the code that queries the recommendation. It needs to be called in two places:
(1) `RecommendedContent` - need to cover the case of floating player + visit another video page.
(2) When video is floating and autoplayed the next video.
## 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.
