TransactionErrorHandler does not move message to ActiveMQ.DLQ

Issue

• TransactionErrorHandler does not move message to ActiveMQ.DLQ after redelivering 6 times. When the route is in transaction and there is ConnectionException or UnknownHostNameException, it should redeliver 6 times and move the message to ActiveMQ.DLQ instead of losing messages.

• If we run the test using this command: mvn -Dtest=MyTest test then it will have the correct behavior (Got ConnectException, redelivered 6 times and it will eventually moved to ActiveMQ.DLQ) and the message is not lost.

• However, when we run it using mvn camel:run, then send message to the activemq inbox. It will get ConnectException, redelivered 6 times and the message is lost. It does NOT go to ActiveMQ.dlq
  The same thing when we run it on JBoss Fuse.
