Improve overloadings check in generated code #370

[Vassiliy-Kudryashov]

Description

Check for classId was added

Fixes #370

Type of Change

• Bug fix (non-breaking change which fixes an issue)

Manual Scenario

The example:

public interface I1 {
}

public interface I2 {
}

public class E implements I1, I2 {
    public E() {
    }
}

public class A {
    public void foo(I1 i1) {
        System.out.println("I1@A : " + i1);
    }
}

import java.util.Objects;

public class B extends A {
    @Override
    public void foo(I1 i1) {
        Objects.requireNonNull(i1);
        System.out.println("I1@B");
    }
}

Observed code in generated tests for class B:
b.foo(((I1) e));
Here you can see redundant casting that affects readability

Expected code in generated tests for class B:
b.foo(e);
