Improve Version Checker Job Pending Edge Case

When the Job does not schedule we are starting a new Job. We need to determine what the edge case behavior needs to be. At this point, we just start a new job every two minutes.

Start by tracing the Version Checker Job scheduling path and how a pending Job is detected. Determine the intended behavior for an unscheduled Job before changing the current two-minute restart behavior. Done means the pending edge case has an agreed outcome and is covered by tests.
