If a learner changes modes (like upgrades to a verified learner), we will reset their schedule for them. But if they did this before the course started, we would accidentally set their schedule to the current time. So when the course did start, they would already appear to be behind schedule. That's silly. So now we always look at course start time when resetting the learner's schedule. AA-426
