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);
