Fixed an issue where the copy constructor of type `DerivedGeneric` in unit tests was not recognized as compiler-generated code after the commit "`Fixed the issue where the DefaultParameters type in https://github.com/restsharp/RestSharp/blob/dev/src/RestSharp/Parameters/DefaultParameters.cs was incorrectly judged as to whether the primary constructor was used due to incorrect initialization logic of isStruct and isInheritedRecord in the constructor of the RecordDecompiler class.`".
