Fix badge color for running jobs

[Wittiest]

Problem

When a job is running and has 1 attempt, the badge with Attempts has an error color

Solution Implementation

• Resolves Modify error color for Running tab when a job has 1 attempt #1518 by only using the error badge pill when a job has an attached error (from previous execution)
• Removes usage of GoodJob::Job#recent_error from Batches show page and applies the same logic there

I discovered that :finished isn't a valid Job#status but I was able to use finished?. I think I also was able to cover the logic a little better. I appreciate you raising this!!
