Description: AsyncScript not working in async RedisCluster but it does work on a synchronous version

>>> from redis.asyncio.cluster import RedisCluster
>>> cluster = RedisCluster(host='localhost', port=6379, decode_responses=True, protocol_version=2)
>>> LUA_SCRIPT = '''
if ARGV[2] == redis.call('GET', KEYS[1]) then
    return redis.call('SET', KEYS[1], ARGV[1])
else
    error("key has changed")
end
'''
>>> cluster.register_script(LUA_SCRIPT)
Traceback (most recent call last):

Could you try the latest version? I believe #2420 solved the issue.
