Don't recur day-of-week recurring items same day

When a day-of-week recurring item is done on the day it's due,
we don't want to recur it on the same day.  Instead, we want to
recur tomorrow at the earliest.
I think we want to avoid recurring a task that has a day-of-week pattern today.  If it's Monday and I need to take the trash out today, and I do, I don't want the task recurred until next Monday.  The change here was to advance a day if today matches the target day, so we'll recur tomorrow at the earliest.
