Make it more likely that cancelled jobs won't end up in ERROR state

[labkey-jeckels]

Rationale

There's a race condition for whether a job will end up CANCELLED or ERROR after it's cancelled. Making the job remember that it was cancelled prevents it from setting it to ERROR later

Changes

• Accurately track cancelled state in the job itself
• Reorder job logging to make sure we don't lose message

Most recent changes have gotten the DataIntegration suites passing. BVT-EHR failures are unrelated. Adam has a fix pending.
