Address review: rename to trackName, use isBlank, point at merged extractor

- serviceName -> trackName, since 'service' means YouTube/SoundCloud
  elsewhere in this codebase.
- isEmpty() -> isBlank(), per review suggestion.
- Extractor dependency now points at TeamNewPipe/NewPipeExtractor at
  the commit that merged (#1551), instead of my fork.
