Delete "Retrieved" invitation from the table once the user has been removed as a domain manager

[vickyszuchin]

Issue description

Currently, the application does not delete the retrieved invitation record of a user who has been removed as a domain manager. It may be confusing to see a retrieved invitation for someone who is not a current domain manager. We should delete the associated Retrieved invitation when removing a domain manager.

Acceptance criteria

• [ ] The User should not see any "Retrieved" invitations of users who were removed as domain managers

@abroddrick, is there anything in this proposed feature that might limit our ability to show (in a future "activity table") that at a point in a domain's history someone was a domain manager?
