Coverage cleanup (#2328)

- Stop running daily service tests in the main repo (since they're now handled [over here](https://github.com/badges/daily-tests)
- Add coverage and separate daily tests badges with links to coveralls
- Update our coverage ignores
    - Move scripts, which do not need coverage, into `scripts/`
- Split out coverage test for npm package
- Remove spurious env var
