Added --all flag to c8 commands

refs https://github.com/TryGhost/Toolbox/issues/203

- without `--all`, c8 will ignore files that aren't covered in tests, so
  they won't pull the test coverage down
- this means we have artificially high coverage scores
- this commit adds `--all` where previously missing
