Fix LyricsWiki scraping code
Fix LyricsWiki scraping code

LyricsWiki now escapes song lyrics using HTML entities (presumably to
prevent scraping), so we now unescape these before parsing.

LyricsWiki has also added a script tag inside the div we are scraping,
so we have to remove this using `scrape_lyrics_from_html`.
