Improve how subsonic ServceGatArtistInfoTwo is retrieving similar artist

[xaviercrochet]

Hey there

I made the following improvement to /getArtistInfo2

I realized that, as lastfm.artist.getInfo as only retrieving a couple of artist, /getArtistInfo2 was most of the time returning very few (or no) similar artists.

• Retrieve similar artists using ```lastfm.artist.getSimilar``
• Match similar artists result with internal database in one single sql query, using a similar pattern as we used for ServeGetSimilarSongs and ServeGetSimilarSongsTwo

cool thanks!

actually I just realised that with this change we never return any artists that aren't in the database (not respecting the includeNotPresent param) so I adjusted the commit to be a bit more similar to how it was, just using the lastfm.ArtistGetSimilar

does that seem ok to you?

Yes this will do the trick, thanks!
