    Ticket 49071 - Import with duplicate DNs throws unexpected errors
    
    Bug Description:  When an import fails there are unable to flush error
                      messages.
    
    Fix Description:  When an import fails close the database files before
                      deleting them.
    
                      Also fixed a small issue in DSUtil where we did not properly
                      check if an entry was valid.
