Issue Summary:
When we try re-activating the user using the Activate a User API, we do not see any record in the Org Audit log.
However, when we deactivate an account using the Deactivate a user API, by creating an API Key, we see a record in the Audit log.

Steps to reproduce:
Run the API for a user de-activation by creating an API Key
POST /users/{account_id}/manage/lifecycle/disable

We should see a record in the Org Audit log, whereas when we run the API for user activation
POST /users/{account_id}/manage/lifecycle/enable, we do not see any data in the Org Audit log.

Workaround:
No workaround available currently and we can only navigate to the user profile to verify the user activation.
