Fix issues with dependency injection

• Description: Fix issues with dependency injection
• Tested with Shopware version(s): 5.6.2
• Tested with PHP version(s): 7.2.33

Das Problem war, dass 3rd Party Plugins Shopware Core Klassen dekorieren und daher die Klasse nicht mehr den selben Namen/Namespace hat. Deshalb haben wir die Dependency Injections in der Service Registrierung angepasst um das Problem zu beheben.
