Deal with inner classes access modification

[lmove]

When an inner class decreases its visibility (e.g. protected to private), Maracas does not report type dependency cases where the class is used through a child class.

public class C extends A {

    public void instantiatePro2Priv() {
        AInner c = new CInner();
    }

    public class CInner extends AInner {
    ...
    }        

In the previous code, we get no detection related to method instantiatePro2Priv() when AInner changes from protected to private.
