Add UnDeserializableValue to DataModelSerializationRoundtripTest

This roundtrip test failed because both the new and the legacy
unserializer (in Lib) checked the hash. This can't work if the
hash was (partly) created by the UnDeserializableValue class.

All hash ckecks are now removed from the new serializer.

This removes the last remaining check from the old serializer. See
