Add one-time migration to purge stale Deezer metadata cache

Browse source 
Deezer album entries cached from /artist/{id}/albums lack artist info,
and track entries from search results lack track_position. Purges all
Deezer album/track cache entries on first startup so they repopulate
with complete data.
