MusicBrainz album ID not returned in getAlbumInfo2

gonic version: 0.16.2

git commit: g2e2a6c3

The getAlbumInfo2 endpoint does not return the MusicBrainz album ID, even if known. E.g. this is the response for an album from my collection with ID al-350:

<subsonic-response status="ok" version="1.15.0" xmlns="http://subsonic.org/restapi" type="gonic" serverVersion="0.16.2" openSubsonic="true">
  <albumInfo>
    <notes></notes>
    <musicBrainzId></musicBrainzId>
    <lastFmUrl></lastFmUrl>
  </albumInfo>
</subsonic-response>

Note the empty musicBrainzId. Looking at the database the album_infos for this entry is the same:

id	created_at	updated_at	notes	music_brainz_id	last_fm_url
350	2023-12-28 13:24:40.554462075+01:00	2023-12-28 13:24:40.554590233+01:00

But the album table does contain the necessary data:

id	tag_brainz_id
350	9cf39057-52d2-4271-adaf-49cc339a7aaf

I'm not sure why there are redundant fields for the MusicBrainz release ID. But it is either not properly transferred to the album_infos table or the getAlbumInfo2 endpoint uses the wrong data field.

Thanks for the fix. Now I also understand this better and see how the Info endpoints are primarily populated by last.fm API data.

But the new behavior makes a lot of sense.
