    backend: RedisLogHandler bugfix
    
    Doing `event = json.loads(raw["data"])` wasn't correct since the
    `redis.lrpop()` actually returns directly the data (compared to
    `redis.sub()` which contained message structures.
    
    This fixes bug caused by 48c101ea5400f76cbe68ccece2f117b06cd3316d.
