In `orderedConsumer.reset()`, `retryWithBackoff()` is returned from with `false, nil` in case the subscription is closed. In this case, `var cons Consumer` is still `nil`, and the code crashes in the attempt to cast it to a `pullConsumer` later on. Fix this by catching the `nil` case explicitly.

There was a problem hiding this comment.
The only case for errOrderedConsumerClosed is when its stopped, so there is no point to try resetting it again, right?
There was a problem hiding this comment.
Yes, there is no point. I used continue here because when the consumer is stopped we'll eventually end up in <-sub.done case where the actual cleanup is performed.
