JDG tomcat session externalization: session is not passivated properly in case of FINE persistenceStrategy

After the JDG-2618 is fixed, new issue started to appear for Tomcat 7/8.
We have a test which tests Session Passivation/Activation. The issue is that after session creation the session is not passivated. It is passivated after each next call to the same session but is not passivated after exactly the first one.
This happens when `persistenceStrategy` is set to `FINE`. With `COARSE` this doesn't happen.

This is the specific test failure: https://jdg-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/jdg-func-session-externalization-eap/lastCompletedBuild/CONFIG=XSITE,container=tomcat8,jdk=java18_default,label_exp=RHEL7,strategy=FINE/testReport/org.infinispan.test.sessionext.jee/JeeSessionExternalizationIT/testSessionActiovationAndPassivation/

The code for the test is located:
