Generating fake “to Recents” events for overview NOT from task 

These records are required by “Transition Delay - Hot Launch From
Recents” test. It doesn’t look at transition times for this event. They
are just a part of its expected sequence of events.

I generate transition delay times as zeroes because no one is looking at
them.
