Test to check if Certmonger tracks certs in between reboots/interruptions and while in "CA_WORKING" state
    
    When a resubmit request is submitted an "invalid cookie"
    error message is no longer shown
    
    Earlier an "invlaid cookie" error message was shown when getcert list was called.
    
    The fix allows an empty cookie in dogtag-ipa-ca-renew-agent-submit
