Transactional Authorization tree authentication outcomes do not appear to be audited or monitored

Bug description

From static analysis, it appears that org.forgerock.openam.core.rest.authn.trees.SuccessProcessTreeResult#process and org.forgerock.openam.core.rest.authn.trees.FailureProcessTreeResult#process exit without auditing or monitoring the authentication outcome when the authentication is in support of transactional authorization.

How to reproduce the issue

1. Perform transactional authorization using an authentication tree to perform the authentication
2. Check the authentication audit log and authentication monitoring metrics after completing the authentication part of transactional authorization

Expected behaviour

The outcome should update audit logs and metrics.

Current behaviour

The outcome likely does not update audit logs and metrics. (needs to be confirmed by investigation).
