SimpleCov Reporting Differences Between v0.17.1 and v0.18.0

[ksylvest]

I'm running simplecov / codeclimate. Bumping from v0.17.1 to v0.18.0 of SimpleCov causes the reporter to fail:

#!/bin/bash -eo pipefail
curl -L https://codeclimate.com/downloads/test-reporter/test-reporter-$CC_TEST_REPORTER_VERSION > ./cc-test-reporter
chmod +x ./cc-test-reporter
./cc-test-reporter format-coverage -t simplecov coverage/.resultset.json
