xautoclaim fails to decode request in there are no messages to claim

Calling `xautoclaimOpts` on an empty stream leads to an exception:

```
RedisException {redisExceptionReply = MultiBulk (Just [Bulk (Just "0-0"),MultiBulk (Just [])]), 
```

Debug in redis:

```
host> XAUTOCLAIM stream group consumer 60000 0-0
1) "0-0"
2) (empty list or set)
3) (empty list or set)
```
