Found the order at https://docs.travis-ci.com/user/customizing-the-build/.

In nylas/N1@d95cb45147 the entire build script
was merged from Evan Morikawa, which reordered the whole Travis build script.
athis commit reorders the to have the Travis build environment config at the
beginning of the script and the build process at the end and the Travis
secure variables at the end of the script.
