Off by one error in redis_response.dart

[marianhlavac]

Unfortunately I don't have full debug information or Redis response on which this occurs, but only access to a error stacktrace, indicating that there's a off-by-one error in redis_response.dart when handling response that is a list.

The command on which this error happens was SMEMBERS.

ArgumentError: RangeError (length): Invalid value: Not in inclusive range 0..650: 651
