Remove feature set status check for job update requirement

[khorshuheng]

What this PR does / why we need it:

Currently, a job is deemed to require update if one or more associated feature set is in pending state. This leads to infinite loop in which the job manager keep updating existing task but the job status never becomes successful:

1. New feature set is created, and status is pending.
2. Job submitted.
3. In the next job polling, requireUpdate is called, and return true because status of the feature set is pending.
4. Dataflow job is updated, eventhough it's not supposed to.
5. Job status update is skipped.

Feature set equality check should have sufficed to determine if a job requires update.
