LMS sends artist coverArt ID even if there is no cover art

[splintering]

It seems LMS is sending a coverArt ID for artists over the OS API even if the artist has no cover.

This leads to obsolete requests from clients (in my case Symfonium) for the cover art which always and predictably end in a HTTP 404:

2024-03-15 17:48:32.681 Error/ImageCacheManager: Error downloading image [404] - http://192.168.xx.yy:zzzz/rest/getCoverArt.view?id=**ar-11**&u=REDACTED&p=REDACTED&v=1.13.0&c=Symfonium&f=json

I think there is now way for the clients to predict the result, so the proper behaviour would probably be to not send a coverArt ID if no cover art is there?

Ah yes you are right, I forgot about this problem. Thanks for reporting!
