If an exception is occured during a model saving then the model is questionable left in the serialized state (_serializeFields is called, but unserializeFields is not called)

Hi, @dfediuk

Thanks you for reporting. Created internal ticket MAGETWO-47887 for investigating

[dsikkema-magento]

@dfediuk object in memory will be left in serialized state, exception will be caught and re-thrown, and persistent storage will not be corrupted. Is that correct? Can you elaborate on the harm from not calling unserializeFields?

Closing for now, please re-open if you find any reasons why the current approach is unsafe.
