Broker displays incorrect message count after failback

There is a test-case.zip attached to JIRA. This is simple reproducer, unzip it and run " mvn package" command to build it. In the resources directory there are two files broker.xml.master and broker.xml.slave. Use those to start your master and backup brokers. You may need to edit them and change the host name. Before running reproducer edit the jndi.properties file and modify the host name used in your tests. To run use command "mvn exec:java". The reproducer creates 10 durable susbscribers on a topic called testTopic. Two of those subscribers are slow with message processing. Start master broker followed by back broker using configuration provided. Once they are running start the reproducer and wait until all subscribers are created. Then using load generator start publishing messages on master broker to testTopic. Wait until you see in master log file that the testTopic started paging. Few few minutes more then "kill -9" master broker. Using cli query the testTopic stats they should show number that don't make sense. After 5 minutes performa fail back by restarting master and again using cli query stats for tesTopic.
