Subject: C++: fix dereferencing of nested type and operator '->'

Fixed case:
template<class T>
struct List
{
  struct iterator
  {
    T *operator->() { return &t; }
    T t;
  };
  iterator begin() { return iterator(); }
};

struct Foo { int bar; };

void func()
{
  List<Foo> list;
  list.begin()->; // code completion doesn't work
}

Task-number: QTCREATORBUG-13799
