[issue23487] argparse: add_subparsers 'action' broken

Of course it makes sense. If you e.g. want the action to be 'append' so that the subparser-name is appended to a already existing list / or to create a new list with the subparser-name as first argument.
E.g.:

parser.add_subparser(dest='foo', action='append')
parser.parse_args('bar').__dict__ == {'foo': ['bar']}
