Fix allow_duplicates not working for singles in watchlist scanner

Browse source 
Singles like "idol" weren't added when the same song existed on a
different album because check_track_exists used album-aware matching
that found the track via album name. Now skips the album hint when
allow_duplicates is on so matching is title+artist only, then compares
album names ourselves with a strict 0.85 threshold. Only affects users
with allow_duplicates enabled.
