Bookmark should return a denormalized entry

[Glandos]

As I test bookmarks in Ultrasonic, I notice that they're displayed without any details, even if they work. I've then got a list of unlabeled entries.

I've taken a look into Navidrome: https://github.com/navidrome/navidrome/blob/master/server/subsonic/bookmarks.go#L26
And Nextcloud/ownCloud music: https://github.com/owncloud/music/blob/master/lib/Db/BookmarkMapper.php#L31

They all de-normalize the bookmark entry, by returning the whole media details along with its ID, instead of just the ID. It seems that the client is not expected to do a second request to get media info.

I had a quick look at gonic, but I don't know have any idea to implement it for now.

Works like a charm, thanks!
