Can't find by name lookup field with type TFIBWideStringField

[RonaldsR]

Fix:

function TFIBWideStringField.GetAsString: string;
begin
if fieldKind=fkData then
if GetDataToReserveBuffer then
Result:=PWideChar(FReservedBuffer)
else
Result:=''
else Result:=inherited; //Use inherited when field not fkData.
end;
