[Missions] Refactor: Added a new slot
Mission.isPersonalInformationProcessed to help determine the state of
processing for each process (run InitSlotPersonalInformationProcessed
WriteCustomTask to migrate data).
[Missions] Refactor: PERSONAL_INFORMATION_PROCESSING MissionState is
only required if at least one participant has an AccountabilityType with
a information processing queue associated.
[Missions] Bug Fix: ArchiveItemActivity no longer sends out-of-context
emails about the authorization of participants.
