Date/Time of the first activity in a repeat activity sequence is wrong if you choose a start date in the repeating section

1. Create an activity.
2. In the repeat activity section choose a start date/time.
3. When you click save the confirmation popup seems to have the correct date/times all listed.
4. The first activity that gets created has the activity date/time from the original (which is likely the current date/time), not the start date you picked.

Can reproduce on dmaster.demo
