Fix scope lookup for template parameters containing unary scope operators

Fixes cases like:

namespace Alloc {
  template<typename T> struct Rebind {
    typedef int Integer;
  };
}
%template(RebindBucket) Alloc::Rebind< Bucket >;
OR
%template(RebindBucket) Alloc::Rebind< ::Bucket >;

Alloc::Rebind< Bucket >::Integer Bucket1() { return 1; }
Alloc::Rebind< ::Bucket >::Integer Bucket2() { return 2; }
Alloc::Rebind<::template TemplateBucket<double>>::Integer Bucket3() { return 3; };
