Replace Kotlin setters with direct property access for models from Fuzzer #1241

[volivan239]

Description

Previously calls to Kotlin setters in Fuzzer models were not replaced with direct accesses because check fieldId.setter == methodId failed due to different types of operands (MethodId vs FuzzerMockableMethodId, see ExecutableId.equals()). Now this check is rewritten with new method describesSameMethodAs that checks only declaringClass and signature but ignores javaClass.
