Fixes ALF-10846: A system error happened during the operation: Error while evaluating expression.

- A simple fix whereby the task is routed to admin if the initiator of the process no longer exists. Since the affected tasks are simply a courtesy to the initiator to inform them that the work was done, it seems churlish to prevent the assignee from ending the task if the initiator has been removed from the system. Other, more complex, alternatives were considered including adding a gate to route the process directly to "end" if the initiator no longer existed, but it seemed overkill, really.
