[kronolith] reminders are sent to wrong account

[Per olof Ljungmark]

Running latest -STABLE of Horde, Kronolith, Imp, PHP4.4.
When entering a new event and setting a reminder, it is sent to the 
wrong e-mail account. Worse, I had it working before and I have no idea 
what I did to break it.

If I look in the database table the calendar events look ok and is 
assigned to the right user.

Could someone please point me to where the recipient of an alarm is 
actually looked up?
