(buildkite 6/n) Get coverage working again
Coverage reporting has been broken / not running for ~2 months. This diff fixes it and gets coverage working again.
- Rename coverage-image to buildkite-coverage for consistency.
- Disable coverage on tests where coverage is not working correctly
- Disable broken lcov for js_modules (we weren't using it anyway) - we should fix this at some point FYI @dish
Depends on D5775
