Improve director unwrap detection for the return type

Browse source 
Resolve the return type to correctly determine if the type is a pointer or
reference to a director class.

SwigType_refptr_count_return() recently added as a simpler fix is no
longer needed.

The conventional approach of using the "type" rather than "decl" to
analyse the return type is used instead too.
