Subject: C++: template base class and default argument for template class

Fix code completion for case:
struct Foo
{
    int bar;
};

template <typename T>
struct Base
{
    T t;
};

template <typename T1 = Foo>
struct Derived : Base<T1>
{};

int main()
{
    Derived<> foo;
    foo.t.// no code completion
    return 0;
}

Task-number: QTCREATORBUG-12606
