[AMQ 7.0] JMX attributes "Mesage count", "Messages added", "Message acknowledged" get out of sync

Issue

• Its possible that the queue JMX attributes "Mesage count", "Messages added", "Message acknowledged" get out of sync. Sometimes hawtio reports a higher value for "Messages added" than "Message acknowledged" while "Message count" is 0 and all messages got correctly consumed by the connected consumers.
