Allow Secondary Users to remove hosts from their own account view

Description: Secondary Users currently can’t remove a host from their own Hospitable account. Only the Primary User (the host) can remove a Secondary User via Settings → User Management → Delete user. This forces Secondary Users to contact former hosts to get removed, which is awkward and creates clutter when clients are no longer worked for. Please add a “Remove Host” or “Leave Account” option in the Secondary User’s settings so they can clean up their own list without needing the host to act.
