Once a user has unsubscribed, every other attempt to unsubscribe creates a log entry

Create a newsletter, send it and unsubscribe at least twice.
I think consecutive unsubscribes shouldn't yield PHP exceptions -- the purpose of unsubscribing is not to be in a subscriber's list, and this is already the case. If there has to be a message whatsoever, it should be more like "simplenews: subscriber not found" (or the like) message. Sort of a warning not an error.
