DATAREDIS-170 - Cancel SubscribtionTask can leave connection open.

RedisMessageListenerContainer did not properly close connections if the subscription was canceled immediately after staring the container. Since DARAREDIS-242 the container waits for the subscription to complete and therefor no more connections remain open.

Additionally added missing parameters to run tests with JRedis.
