    Remove useless run_periodic_tasks call in ClientRouter

    The only periodic task (_remove_stale_clients) in ClientRouter was
    removed in change I10f374adca672576058c4dbab708c040d166df47 and this
    isn't the correct way to run periodic tasks repeatedly anyway (this
    will only run them once upon ClientRouter.__init__), so remove the
    useless call.

    This also removes a functional regression test which was testing only
    this specific code path, where the intended periodic task ran only
    once upon init of the compute service. All other periodic tasks in
    compute are disabled by default in functional tests.
