Remove requirement to mark model as serializable to be constructed by ObjectCreator

[Voiteh]

We shouldn't be using deserializationContext as it is ment to be used when there is hierarchial dependency between not provided attributes. In our case we always have all required attributes provided. There may be problem though for selecting constructor or providing fields allready initilized so clazz.apply(....) may throw here. Further investigation will be needed. Although running unit tests in all modules should indicate problems.
