Subject: IntegrityMonitor check before commit

Under some conditions the JPA transaction may be already closed
when commit is called in StateManagement. Surround it with a
check to see if the transaction is active, so it will not
generate an error in the log.

Issue-ID: POLICY-484
Change-Id: Id54585e68361a0be9ae8afd7e9ccba2f7eadfe5f
