Persistent subscriptions are not invoking the FailureHandler

[carlosgoias]

Describe the bug If you create persistent subscription with the configuration with FailureHandler settings, it's not being called, even using the ThrowOnError = true

To Reproduce Steps to reproduce the behavior:

private static Task RetryEventProcessingFailureHandler(
        EventStoreClient client,
        PersistentSubscription subscription,
        ResolvedEvent resolvedEvent,
        Exception exception
    )
{
    return subscription.Nack(PersistentSubscriptionNakEventAction.Skip, exception.Message, resolvedEvent);
}
...
services.AddSubscription<AllPersistentSubscription, AllPersistentSubscriptionOptions>(
    "PaymentIntegration",
    builder => builder.Configure(cfg => 
    {
        cfg.FailureHandler = RetryEventProcessingFailureHandler;
        cfg.ThrowOnError = true;
        cfg.EventFilter = StreamFilter.RegularExpression($"^{testId}#");
    }));

Expected behavior FailureHandler should be called.

Screenshots I suspect the problem is in this part PersistentSubscriptionBase, the line 198, is if(Options.ThrownOnError) throw exception, and never calling the line 202 with the failureHandler.
