Describe the bug
Ask will not throw exception when the response is Status.Failure

This is caused by the order of case statements in FutureActorRef<T>.TellInternal:

            switch (message)
            {
                case ISystemMessage msg:
                    handled = _result.TrySetException(new InvalidOperationException($"system message of type '{msg.GetType().Name}' is invalid for {nameof(FutureActorRef<T>)}"));
                    break;
                case T t:
                    handled = _result.TrySetResult(t);
                    break;
                case null:
                    handled = _result.TrySetResult(default);
                    break;
                case Status.Failure f:
                    handled = _result.TrySetException(f.Cause
                        ?? new TaskCanceledException("Task cancelled by actor via Failure message."));
                    break;

when T is object and message is Status.Failure the case T t: is executed instead of case Status.Failure f:.
