[BUG] @ExtensionMethod methods from parent class are not recognized

[iocmet]

Describe the bug
When trying to call extension method on class that extends extension method target class, compilation will fail, that gonna work only if class is upcasted to its parent

To Reproduce

public class Test {
}

@ExtensionMethod(TestExtensions.class)
public class Test1 extends Test {
    public void test() {
        System.out.println(this.testExtensionMethod()); // Error
        System.out.println(((Test) this).testExtensionMethod()) // No error
    }
}

@UtilityClass
public class TestExtensions {
    public static String testExtensionMethod(Test instance) {
        return "testString";
    }
}

Expected behavior
No error
