Generated code tries to use private class as a type

[sofurihafe]

Description

Generated code tries to use private class as a type for expectedResult argument.

To Reproduce

1. Generate parametrized tests for VoidStaticMethodsTest from utbot-samples.

Actual behavior

ClassWithStaticAndInnerClasses.PrivateInnerClassWithPrivateField type for expectedResult in arguments cannot be accessed because it's private.

@ParameterizedTest
@MethodSource("provideDataForUsePrivateInnerClassWithPrivateField")
public void parameterizedTestsForUsePrivateInnerClassWithPrivateField(
    ClassWithStaticAndInnerClasses classWithStaticAndInnerClasses,
    int int1,
    ClassWithStaticAndInnerClasses.PrivateInnerClassWithPrivateField expectedResult,
    Class<Throwable> expectedError
) throws IllegalAccessException, NoSuchFieldException  {
    <...>
}
