commit e1ae89e9f110cf4af75f6ea82a38a9ce085617ac
Author: Endi S. Dewata <edewata@redhat.com>

    Fixed problem searching the latest certificate request.
    
    Previously if a certificate request page only has one entry the
    entry itself will be removed from the page, resulting in a blank
    page.
    
    The QueryReq.trim() has been modified not to remove the marker
    entry if it's the only entry in the page.
