DB Inconsistencies when revoking a publisher agreement

[netomi]

What usually happens is that the versions of all published extensions for that user are set to inactive, however the extension entity itself is still kept active leading to a situation where there is an active extension without any version.

Follow up error when the DB is in such an inconsistent state:
