Description

Tracking down in intermittent failure of org.apache.activemq.network.DemandForwardingBridgeTest.testSendThenAddConsumer

the problem turned out to be a decrement of the dispatched count when the consumer was removed.
So before the removal, most of the time, the stat was 1, and the test passed. But if the removal was complete, the dispatched count was decremented in error by the unacked message count. This is wrong. The dispatched stat needs to reflect what happened Otherwise it tracks the dequeue count.
