Be able to user UptadedBy function with disabled users

Issue Summary

The updatedBy function only works with actives users, if I disabled a user and use this function, it doesn't bring the correct result. However, the status changed query works and pull out the information made by the disabled user. The query that I'm using for updatedBY is:

issuekey in updatedBy("<username>") order by created DESC

Steps to Reproduce

1. Create issues with a user
2. Disable the user that create the issue.
3. User the query: 

    issuekey in updatedBy("<username>") order by created DESC   

Expected Results

Since the updatedBy pull out the issues created by a user, the expected result is to those issues be shown after I used this function.

Actual Results

No issues were shown since the user is disabled.

Workaround

No workaround.
