When gc.reflogExpire and gc.reflogExpireUnreachable are set to "never" and --stale-fix isn't in effect we *could* exit early without pointlessly looping over all the reflogs. However, as an earlier change to add a test for the "points nowhere" warning shows even in such a mode we might want to print out a warning. So while it's conceivable to implement this, I don't think it's worth it. It's going to be too easy to inadvertently add some flag that'll make the expiry happen anyway, and even with "never" we'd like to see all the lines we're going to keep. So let's assert that we're going to loop over all the references even when this configuration is in effect.
