When bulk subscribing reminders at a time of day earlier than the current time, any reminders that fall between the two points in time are not sent.
Example: given a reminder with a single message that is sent at 1 hour after subscription. At 10:00 GMT, bulk subscribe a user to that reminder with Message time of day of 8:00 GMT. The message will be scheduled for 9:00 GMT, and dropped by Remindem since it should be delivered in the past.
Expected: either schedule the first message to be sent at 9:00 GMT of the following day, or display a warning indicating which messages will be lost.
