Repeating reminders first sent in a different tz will have incorrect repeat length

[MaddyUnderStars]

If a reminder is sent in one tz, and it's notification will be sent in a different tz ( eg daylight savings ), we calculate if this is a into or from DST transition and subtract/add an hour accordingly.

However, for repeating reminders, this code is never run again. And so repeating reminders have their length set an additional hour in either direction to account for that first tz change.
