Reports different results at an umbrella level vs in-app level

[srevenant]

If I run mix coveralls at the umbrella level it reports different results (more files/lines missed), then when run within each app.

mix coveralls reports different results than mix cmd mix coveralls

For now we'll just switch to the latter and parse it by hand w/a CI script in python, as I've spent enough time trying to figure out where the problem lies.

If you want me to dig up some info, please let me know, I'm happy to dig things up.
