Mapping registration problem

[careless6666]

We have registration in library here

https://github.com/Farfetch/kafkaflow/blob/master/src/KafkaFlow/Middlewares/TypedHandler/Configuration/TypedHandlerConfigurationBuilder.cs#L113

foreach (var handlerType in _handlers)
        {
            _dependencyConfigurator.Add(
                handlerType,
                handlerType,
                _serviceLifetime);

            var messageTypes = handlerType
                .GetInterfaces()
                .Where(x => x.IsGenericType && typeof(IMessageHandler).IsAssignableFrom(x))
                .Select(x => x.GenericTypeArguments[0]);

            foreach (var messageType in messageTypes)
            {
                configuration.HandlerMapping.AddMapping(messageType, handlerType);
            }
        }

And it is a big problem if you will use your interfaces inherited from IMessageHandler

example

public interface IPersistantMessageHandler<TMessage> : IMessageHandler<TMessage> where TMessage : EventBus.Messages.Models.Message
{
    Task OnRetryExhausted(IMessageContext<TMessage> message, CancellationToken token);
}

In this case we will have double handler registration because it is resolved as IMessageHandler<TMessage and IPersistantMessageHandler and mapped to single message. It is really strange, because i use only one registration

.AddTypedHandlers(h => h.AddHandler<HelloMessageHandler>())

and expect only one call after instead of double

And I haven't found any way to fix this mapping configuration.
