Important: #67401 - Dependency Injection is now done before initializeObject()

See forge#67401

Description

Formerly initializeObject() was called before the dependencies were injected when retrieving an Extbase Domain Model. This behavior didn't match either the documentation nor the behavior when using the ObjectManager.

With TYPO3 CMS 7.3 this has been changed, dependency injection using @inject annotations and inject*() methods is now performed before calling initializeObject() when retrieving Domain Models.

This may have impact on extensions that are relying on the reversed call order. In these cases adjustments are required to take into account that the injected objects are available.
