Exception in .CustomAction results in losing the message

[aherba-krk]

When using wolverine with rabbitmq, throwing an exception within .CustomAction, like this:

opts.Policies.OnAnyException().CustomAction(async (runtime, lifecycle, exception) =>
        {
            throw new Exception("Exception in custom action");
        }, "customAction");

results in wolverine losing the message, as if it was processed successfully.

I think it's due to this catch:

@aherba-krk What do you mean the message is lost? Just that it's discarded? What are you actually trying to do with your custom action?

And this is Wolverine working as intended, so I'm moving this off to a discussion
