Issue Summary

The /rest/api/3/users and /rest/api/3/users/search endpoints are returning a total number of results that is larger than the number of users reported on the user management page

Steps to Reproduce

1. Add 15 users to your site
2. Delete 5 managed accounts out of the 15
3. Install some Jira add-ons
4. Verify that you 10 users reported on the site's user management page.
5. Use the following endpoint (Return 10 results starting at index 10)

/rest/api/3/users?maxResults=10&startAt=10

Expected Results

There should be no results as there is only 10 users in the site's user management.

Actual Results

Results are returned.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
