Breaking: #67402 - Extbase AbstractDomainObject initializeObject

See Issue #67402

Description

Method initializeObject() has been removed from TYPO3\CMS\Extbase\DomainObject\AbstractDomainObject.

Impact

Possible fatal error in Extbase if objects are thawed from persistence.

Affected Installations

Domain objects extending AbstractDomainObject and calling parent::initializeObject(). This is relatively unlikely since the default implementation of initializeObject() is empty.

Migration

Remove calls to parent::initializeObject() from own initializeObject() implementations.
