PR c++/71515 - typename in partial specialization

* pt.c (resolve_typename_type): Try to avoid calling
currently_open_class.

Testcase:

template  struct A;
template  using enable_if_t = typename A<_Cond>::type;
template  struct B;
template  struct C;
template  struct D;
template 
struct B> {
  using Base = D;
//  typedef  D  Base; // OK
  using typename Base::Scalar;
  Scalar a;
};

See: PR69481 for a similar issue.
