fix(slint): favorites track row album link did not navigate

The Tracks row routed every media-action through track-action, which
forces kind="track"; an album-name click arrived as ("track", album-id,
"open") and was handled as an artist open, so only the artist link
worked. Route album/artist "open" through the wired open-album /
open-artist actions; everything else still goes to track-action.
