BUG: Can't use day-of-week restriction without time-of-day restriction

There was a bug which prevented a scheduled message with a day-of-week
restriction from being sent unless it also had a time-of-day
restriction. This has been fixed, i.e., it is now possible to use a
day-of-week restriction without also using a time-of-day restriction.
