Use Travis builtin support for codecov and coveralls?

[harryscholes]

Travis now adds codecov and coveralls support:

codecov: true
coveralls: true

https://docs.travis-ci.com/user/languages/julia/#coverage

IIRC that support is kind of broken in that it causes build errors instead of failures. @ararslan could you comment?

[ararslan]

Been a while since I've looked at it. I think @simonbyrne would have the most up-to-date knowledge on that, since he's the one who implemented it.

[simonbyrne]

Yes it is broken: I tried to fix it in https://github.com/travis-ci/travis-build/pull/1571, but got stuck.

[harryscholes]

Ahh okay. We could close this for now and maybe implement the changes when Travis is fixed

[christopher-dG]

I'll leave it open, since otherwise I'll probably forget about it :upside_down_face:
