Fixing issue where affiliated task last-active-times were inconsistent.
- We rely on the last-active-times of the task records to order tasks
in Recents, but for affiliated tasks, their last-active-time was never
set until the task was launched. This change just ensures that all
tasks have a valid last-active-time, and for affiliated tasks, ensures
that the task that they were launched behind always has a later
last-active-time.
