Bug in newly added function "RenameInCSV" (SynCommons.pas)

Dear AB,

it seems that there is a bug in your recently added function "RenameInCSV": it does not rename the first item in the CSV list.
Short test code to reproduce this issue:

program TestRenameInCSV;
{$APPTYPE CONSOLE}
{$I Synopse.inc} // define HASINLINE USETYPEINFO CPU32 CPU64 OWNNORMTOUPPER
uses
  SysUtils, SynCommons;
var
  csv: RawUTF8;
begin
  csv := 'old1,old2,old3';
  writeln(csv,' 1 ',RenameInCSV('old1','new1',csv),' ',csv);
  writeln(csv,' 2 ',RenameInCSV('old2','new2',csv),' ',csv);
  writeln(csv,' 3 ',RenameInCSV('old3','new3',csv),' ',csv);
  writeln(csv,' 3 ',RenameInCSV('old3','new3',csv),' ',csv);
  writeln(csv,' 4 ',RenameInCSV('old4','new4',csv),' ',csv);
  csv := '';
  readln;
end.

The result is:

old1,old2,old3 1 FALSE old1,old2,old3
old1,old2,old3 2 TRUE old1,new2,old3
old1,new2,old3 3 TRUE old1,new2,new3
old1,new2,new3 3 FALSE old1,new2,new3
old1,new2,new3 4 FALSE old1,new2,new3

As you can see, the first item "old1" is not renamed as expected.

Edit: And if the csv list contains the same value more than once, only the first found value will be renamed.

Corrected by https://synopse.info/fossil/info/3cb88e1ba2
Thanks for the quick catch!

And the value is expected to appear only once in the list, by definition.
