Solves problem but throws FlareSolverrException

`https://www.tibia.com/community/?subtopic=characters&name=Dummy` can be solved but `FlareSolverrException` is thrown.

The code in `ClearanceHandler.cs` is:

```
// Change the cookies in the original request with the cookies provided by FlareSolverr
InjectCookies(request, flareSolverrResponse);
response = await base.SendAsync(request, cancellationToken).ConfigureAwait(false);

// Detect if there is a challenge in the response
if (ChallengeDetector.IsClearanceRequired(response))
throw new FlareSolverrException("The cookies provided by FlareSolverr are not valid");
```

There is no cookie in `flareSolverrResponse.Solution.Cookies`
