Fix for code coverage file

This is in regards to issue forcedotcom/cli#1725. 

The fix is to simply update no-map by project root directory to force apex-node to find all cls and trigger in working directory. While the fix will work for now, I believe it is still incomplete as it doesn't consider packageDirectories filtering from sfdx-project.json.
