Codecov.yml is not getting detected due to absolute paths

[josh-byster]

Because of the use of process.cwd() to get the path for the yaml file (which the API expects as relative), the path sent to the query is absolute (ex. /var/www/app/codecov.yml) and thus does not take effect online. Likely this is the root cause of #79. the suggested change would be to get the relative path rather than the absolute working directory.

Closing this out as we check for the yaml server-side.
