Fix bug in the RabbitAmqpListenerTests for consumeIsDone

The logic if the `processQ1AndQ2Data()` listener method is to
collect 10 messages, where one of them is a duplication after `requeue`.
The first `discard` is accepted into `received` result, but the second is
terminated by the exception.
However, `countDown()` in the `finally` block is still called for all the cases.
Therefore, `11` times: 7 for normal data, 1 for `discard`, 2 for `requeue`, and 1 for exception.
