Fix some latest test failures

https://build.spring.io/browse/INT-B43-164/

* Fix CheckStyle for `System. out .println(` expression commenting out such a code line
* Fix generics in the `JdbcMessageStoreTests`
* Increase receive timeout in the `FileMessageHistoryTests`
* Change the `AsyncAmqpGatewayTests` logic to deal with the same channel for both `ack/nack`.
The `timeout` case without reply may end up with the `Consumer cancel`, therefore `nack` not `ack` like we expected
