Subject: [PATCH] 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.`".
