Web-scrobbler: Youtube Scrobbling Ignores Categories

Describe the bug
It seems like YouTube doesn't show the categories anymore, and that is breaking the category filtering.

How to reproduce
Steps to reproduce the behavior:

1. Ensure "Scrobble videos from "Music" category" is checked
2. Play YouTube Videos
3. Watch Watch Web Scrobbler try to scrobble non music categories

Expected behavior
Only Youtube Videos in the 'Music' category should be scrobbled

Environment

• OS: Linux
