Issue Summary

When updating a user using API, the profile picture of this user gets removed.
This does not affect the UI administration, where the picture remains, only the API

Steps to Reproduce

1. Select a user to alter details
2. Impersonate this user and add a profile picture
3. Via API, update this user ID (any field) via PATCH or PUT
4. Refresh the impersonated page
5. Notice the profile picture is removed

These steps apply when impersonating a user or login as this user as well

Expected Results

Profile picture should remain when updating a user

Actual Results

Profile picture is dropped when updating the user via API

Also when this issue occurs, if the user applies a new profile picture, the updated picture will not display outside the user's view ( cannot see the new picture in admin, but will display when the user logs in to his account)

Workaround

Currently, updating users via the UI is not affected
