Unnecessary API calls
When converting back and forth between mopidy and qobuz objects, a lot of API calls are being issued to look up all tracks. This leads to timeouts in various clients (e.g. ncmpcpp).
Failing searches
Some edge cases in the search, where the API does not return a performer-id for one track, the complete search will fail.
