Fix loading of class literal constant values in reflection

Browse Source 
This is an addition to c1ab08c8ce where KT-26582 was fixed. The test
testClassLiteralArguments in JvmRuntimeDescriptorLoaderTestGenerated
failed before this change but went unnoticed because it wasn't run on CI
(see the previous commit)
