Album art display issues on Android client (DSub) playback - Airsonic Advanced 11.0.0-SNAPSHOT.20220129204202 (1/29/2022) or newer

## Problem description

Running 11.0.0-SNAPSHOT.20220129204202 (1/29/2022) or newer introduces issues with album art display on Android clients (i.e. DSub). After upgrading to an impacted Airsonic Advanced version the album art for the first downloaded song appears to become globally cached and displayed for all songs/albums thereafter in the DSub client's playback screen.

The expected behavior is that the song's corresponding album art is displayed during client playback as is seen in version 11.0.0-SNAPSHOT.20220124042650 (1/23/2022) or earlier.

### Steps to reproduce

1. Install Airsonic Advanced version 11.0.0-SNAPSHOT.20220124042650
2. Open DSub client on Android and download random sample of songs from various albums. Verify correct album art is displayed on playback.
3. Update Airsonic Advance to 11.0.0-SNAPSHOT.20220129204202
4. Open DSub client on Android and download random sample of songs from various albums. Verify incorrect (cached) album art is displayed during playback from first downloaded song after server upgrade.
5. Clear Dsub client user data and cache, reconfigure normal settings, download random sample of songs from various albums, and verify incorrect (cached) album art is displayed during playback from first downloaded song after server upgrade.
6. Redeploy Airsonic Advanced version 11.0.0-SNAPSHOT.20220124042650 or prior and confirm album art display handling is working in DSub client.
