DATAREDIS-170 - Cancel SubscribtionTask can leave connection open.

`RedisMessageListenerContainer` did not properly close `Connection`s if subscribtion was canceled immediately after staring the container. Since [DARAREDIS-242](https://jira.springsource.org/browse/DATAREDIS-242) the container waits for the subscribtion to complete and therefor no more connections remain open.

Additionally added missing parameters to run tests with JRedis.
