TStringBuilder.toString bug
<!-- See available text formatting: https://gitlab.com/help/user/markdown.md -->
## Summary
Instead of method calling, the result of the function is accessed. Related to https://gitlab.com/freepascal.org/fpc/source/-/issues/41632
## Steps to reproduce
```pascal
program Project1;
{$mode delphi}
uses
SysUtils;
function GetStr: string;
var
sb: TStringBuilder;
begin
sb := TStringBuilder.Create;
try
sb.Append('Hello, world');
Result := sb.ToString(False);
finally
sb.Free;
end;
end;
begin
WriteLn(GetStr());
readln;
end.
```
Print nothing instead of 'Hello, world'
