Subject: [PATCH] Fix allow_duplicates setting not working in watchlist scanner

The setting only affected wishlist dedup but the watchlist scanner's
library check still skipped tracks by title+artist regardless. Now
when allow_duplicates is enabled, the scanner compares album names
and only skips if the same album matches. Same song on a different
album is allowed through to the wishlist.
