Issue Summary

After removing a user in Jira, the filters assigned to the user will be deleted from the instance, leading to Project's boards and Features not being displayed. When these are accessed, a blank page is shown.

(Note: there is also a problem with dashboards getting deleted when a user gets removed. Please see https://jira.atlassian.com/browse/JRACLOUD-76758. 

Steps to Reproduce

1. User 2 creates a new project or filter.
2. Remove User 2 in Jira.
3. With another user, access the project's board or features page for the project created by User 2. 

Expected Results

The board and Features work normally

Actual Results

The Projects that use a filter owned by the delete/deactivate will break.
