bug: Lambda parameter references are not equal

[pvojtechovsky]

The code:

Consumer<Integer> c = (field)->{
	field=1;
};

contains CtParameter field in Lambda Expression and CtParameterReference in body of lambda expression. If I try to check whether these parameter references are equal then they are not

CtParameter<?> param = (CtParameter<?>)lambda.getParameters().get(0);
CtParameterReference paramRef = lambda.filterChildren(new TypeFilter<>(CtParameterReference.class)).first();
//it fails here
assertTrue(param.getReference().equals(paramRef));
