Theme : createdBy field is NULL when theme is created via UI

Issue Summary

Theme : createdBy field is NULL when Theme is created via UI

Steps to Reproduce

1. Browse to Themes grid

3. Check Audit Log. A corresponding entry is shown (as expected)
4. Make an API 2.0 GET call to /rest/align/api/2/Themes/id endpoint
5. Notice createdBy field shows NULL instead of UserID

Expected Results

Object "createdBy": "xyz", should be returned, been xyz is the integer UserID of the user logged in the UI.
