The handler previously assumed there would be at least one entry in the
'files' array in the output JSON. It looks like this in the normal case:
"files":[{"path":"app/models/image.rb","offenses":[]}]
But if RuboCop's config excludes the specified input files, causing no
files to be linted, the output is emptier:
"files":[]
This change causes the handler to treat that case correctly, and also
exit early if the reported offense_count is zero.
