Deprecated code-cov dependency.

[medic-code]

Hi,

I noticed when I did manage to install the dependencies that I got this about code-cov

npm WARN deprecated [email protected]: https://about.codecov.io/blog/codecov-uploader-deprecation-plan/

Looking at the website it looks like its been deprecated now but on a quick glance looks like its not something you install as a dependency. Is this dependency used now ? I looked back in the commit history and see that nyc is used for code coverage rather than codecov.
