remove scenario-file (as a whole) from checks to re-run datapoints

[vtnate]

Resolves CLI issue 237

Pull Request Description

The change in this PR means changes to the scenario-file do not trigger re-running every datapoint (removes it from the 2nd list below).

Documenting out-of-date datapoints:

This check looks inside each datapoint specified in the scenario-file.

• If one of the datapoints does not have a finished.job file or an out.osw file, it is re-run
• If the datapoint folder doesn't exist, it is re-run

If the most recent change to any out.osw file is older than the most recent change to any of the following project-dir files, the entire scenario is re-run.

• in.osw
• feature file
• Gemfile
• Gemfile.lock
• Anything inside the mappers folder
