Log:
https://issues.apache.org/jira/browse/AMQ-3190 - Durable Subscription - missing messages when
selector matching sub resumes after broker restart
the next message id needs to be tracked such that unmatched messages are not ignored from
the indexi after a restart. Tracking it as part of message add
in the ackPositions.
