order - access_specifier_required false alarm for inherited class

[keineahnung2345]

For the following cpp file:

class Dummy {
};

class Foo : public Dummy {
    protected:
    public:
    private:
        class Bar {
            string without_specifier;
        }
}

It gives the following issues:

Class 'Foo' should have an access specifier at first.
Class 'Bar' should have an access specifier at first.

But actually the class Foo have access specifiers.
