Unable to create playlist as non-admin user, error code 50: you aren't allowed update that user's playlist

[fletchowns]

gonic version: v0.16.4

if from docker, docker tag:
if from source, git tag/branch: v0.16.4

I am able to create, edit, and delete playlists when logged in as username admin, using https://github.com/tamland/airsonic-refix as my client.

However, for my non-admin user, I see the following:

2024/08/19 06:50:18 subsonic error code 50: you aren't allowed update that user's playlist

I tested with Symphonium as well and got the same error, leading me to believe it might be something on the gonic side. I double checked the permissions to the playlists directory and they seem fine.

Looks like this issue is already covered by #524
