[issue28086] test.test_getargs2.TupleSubclass test failure

Thank you for making buildbots green Steve.

The intent of 51b635e81958 was avoiding needless copying. But this caused to leaking tuple subtype in case of single var-positional argument without other positional arguments. The intent of tests was checking that tuple subtype is not leaked to called function. There is a bug, but I need to find the place where tuple subtype should be converted to tuple without needless hitting performance.
