Fixed uploading single code coverage to Codecov

fixes https://github.com/TryGhost/Toolbox/issues/583

- we currently upload the codecov for unit tests and e2e/admin tests
  separately
- unfortunately this means that when one submits before the other, the
  codecov % will be incorrect
- this leaves a big red cross on the commit until the other coverage is
  uploaded
- this should fix that by upload the coverage in one step once CI is
  happy
