Subsonic API:support album/artist starring

The "star" Subsonic endpoint in funkwhale requires the id parameter, whereas both id, albumId and artistId parameters are optional in the Subsonic API.

http://www.subsonic.org/pages/api.jsp#star

funkwhale gives an error when one tries to star an album or artist without starring a track n the same call:

{subsonic-response={
    error =     {
        code = 10;
        message = "required parameter 'id' not present";
    };
    funkwhaleVersion = "0.17";
    status = failed;
    type = funkwhale;
    version = "1.16.0";
}}
