Bug description

System Address Book not re-initialized after re-enabling (AIO)

Environment:

• Nextcloud AIO 12.3.0
• Nextcloud 32.0.3
• Ubuntu Server 24.04.3 LTS

Description of the issue:

I disabled the following option in Groupware settings:

Groupware → System Address Book → Disable

After a few days, I enabled this option again.

Since re-enabling it, the System Address Book is not initialized again:

• The System Address Book does not appear to be recreated
• Contacts from the System Address Book are not visible in the Contacts app
• This affects the admin user as well

No further configuration changes were made between disabling and re-enabling the feature.

Expected behavior:
After enabling System Address Book, it should be automatically re-initialized and its contacts should become visible again in the Contacts app.

Actual behavior:
System Address Book remains missing / empty and is not restored after re-enabling.

Steps to reproduce

Mentioned above.
