Leftover from a user in assets permissions cause "NotFoundInsightException: User not found!" exception

The issue appears when editing the permissions meaning adding, or removing users while the unknown user(s) are present.

Users already in the permission group are not affected.

2. Give it permission under the assets object schema roles
3. Delete the user in Jira user management
4. A leftover "unknown" user is left in the schema roles
