Show relative paths in acceptance test output

Just a little cosmetic tweak (which I'm not planning to make a Jira
for).

Strip the working directory prefix from test file paths to display
cleaner relative paths like 'features/task_validate_image.feature'
instead of full absolute paths like
'/home/sbaird/path/to/conforma/cli/features/task_validate_image.feature'
