I confirm that:

• I have searched the existing open AND closed issues to see if an issue already exists for the bug I've encountered
• I'm using the latest version (your issue may have been fixed already)

Version

latest master (0c4c223)

Current Behavior

When MusicFolder is set to a relative path, trying to make media files relative against / turns them into empty strings:

In result, fsys contains only a single entry, and the migration fails with error populating folder table: open : file does not exist because root gets the same treatment and is also an empty string.

Expected Behavior

the database migration passing successfully, i suppose

Steps To Reproduce

1. Set up a new Navidrome instance on the stable version, with MusicFolder set to a relative path
2. Add some music, and make sure it ends up in the database
3. Build latest Navidrome and try to migrate the database

Environment

- OS: Linux
- Browser: n/a
- Client: n/a
