[bug]: User assignment icons are invalid when user leaves

[Pdzly]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current behavior

When i assign someone to a issue and he leaves the icon gets cleared of the issue.

It should either behave like:

It gets removed cleanly from all issues or his icon or a default icon should be shown. ( my opinion )

Steps to reproduce

1. Assign a Issue to a user
2. the user leaves
3. the icon doesnt show it anymore but it is still assigned.
