Use of the special case "when is [blah] on call" does not return correct results

We have only one PagerDuty schedule defined called "Normal"

Resulting in: cboscolo [9:38 AM] pagerbot when is cboscolo on call pagerbotBOT [9:38 AM] CBoscolo is not scheduled to go on any schedule

But if I reference our schedule by name it works. cboscolo [9:39 AM] pagerbot when is cboscolo on Normal pagerbotBOT [9:39 AM] CBoscolo goes on call at 5:00 PM Feb 10 (-0800) for schedule Normal
