Multi-Step forms fail when saving objects in the Form State

[ger4003]

In my usecase the FormState holds asset objects like Neos\Media\Domain\Model\Document or Neos\Media\Domain\Model\Image. When form is rendered with initalized formState having one of the mentioned objects, an exception is thrown:

Absorbed Exception: Notice: property_exists(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Neos\Media\Domain\Model\Document" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide an autoloader to load the class definition in .../Data/Temporary/Development/Cache/Code/Flow_Object_Classes/Neos_Flow_Persistence_Doctrine_PersistenceManager.php line 188

Is related to #126

Thanks again for your report and the PR.
After diving into this I realized that this is actually a very old regression introduced with #101

So I turned this into a bug ticket and will push a PR with a fix ASAP, that will make the configuration feature obsolete.
