[BUG] A song with title "0" cause scanner stopped to scan more music

[dd-han]

Describe the bug
A song with title "0" in ID3 Tag will cause music scanner stopped to scan more music.

To Reproduce
Steps to reproduce the behavior:

1. Download mp3tag.zip and unzip it
2. Create folder on NextCloud and upload the audio which unzipped previously
3. Go to /settings/user/audioplayer and set 'Search for audio files in' to previously created folder
4. Go to /apps/audioplayer/ and expend Settings
5. Click on 'Reset library' and 'Scan for audio files'. I also tired sudo -u www-data php occ audioplayer:scan admin -vv instead Scan on web but there is no error on console
6. Nothing show up in Audio Player library
7. Go to /settings/admin/logging and PDOException is there

Expected behavior
My 30 seconds 440Hz tone should be added to library, or at least it should continue to scan more music not just stopped.

Screenshots

Versions:

• Nextcloud: 28.0.7 / 29.0.3
• Audioplayer 3.4.1

Nextcloud log
Error from /settings/admin/logging with some sensitive information removed (my IP address, my install folder)

Error on my test environment with NextCloud 28.0.7 and Audio 3.4.1

Hello,
thats strange. it should never have an empty title because even then there is a fallback with the filename.
I will have a look
