SerializationDebugger does not handle classes with writeReplace correctly

The following class with not serializable object used through writeReplace will not be caught correctly by the SerializationDebugger

class SerializableClassWithWriteReplace()
  extends Serializable {
  private def writeReplace(): Object = {
    new NotSerializableObjectI()
  }
}

The reason is that SerializationDebugger does not check the type of the replaced object (whether serializable or not).
