Fix small bug with clearing swap request counter when an expt appears to have gone active again. If you gave it a higher time than the default, and an idle expt hadn't been idle that long, it would clear the counter when it shouldn't, making idle expts look like they may have gone active again. (It didn't ever change any slothd data or cause any activity, you'd just "forget" that you'd already been sending swap requests. And it only had an effect when you picked times _higher_ than the default idle time.)
