    Relax handling of bad numeric values in the DOM parser.
    
    string_to_gnc_numeric returns a nullptr if the GncNumeric string
    constructor decides that the denominator is 0. The 2.6 version of the
    function didn't check for this and occasionally stored error values.
    Convert that to gnc_numeric_zero to allow the file to be processed.
