Issue 50779 - lib389 - conflict compare fails for DN's with spaces
    
    Description:  When processing the attribute nsds5ReplConflict we were
                  splitting the value into its 3 components:
    
                      namingConflict (ADD) ENTRY_DN
    
                  But we split the "spaced out" values one too many times,
                  and that broke the entry DN if the DN contained any
                  spaces.
