> It was observed that when a workflow is submitted and the Controller attempts to schedule
its tasks, ZK read fails to read the appropriate job's context, causing the job to be stuck
in an unscheduled state. The job remained unscheduled because it had no currentStates, and
its job context did not contain any assignment/state information. This RB fixes such stuck
states by detecting null currentStates.
> Changelist:
> 1. Check if currentState is null and if it is, manually assign an INIT state
