    [gnc-unicode] Use unicode_compare_internal for gnc_unicode_compare_identical
    
    instead of strcmp. strcmp does a byte-by-byte numerical
    comparison, not an alphabetical one (e.g. A > e).
    
    Also fix the transposed args in the strstr call in
    gnc_unicode_has_substring_identical.
