    dconf update: don't warn on a key set twice
    
    It is expected that users may have the same key set multiple times if
    they use separate files in an 'override' type of situation.  In this
    case the higher-numbered file wins and we should silently ignore the key
    set in the lower-numbered file.
    
    This silences the warning message that we previously issued in that
    case.
