Fails with nyc --all #38

When using this coverage instrumenter instead of nyc's one, I get an exception when I add the --all flag. It work without the flag, so I think it is a problem with the instrumenter, not the reportet.

nyc --source-map=false --require babel-core/register --all --instrument=false --reporter=html --report-dir reports/coverage/ npm run test-simple
