Check CI coverage for Python versions

[joerick]

Let's figure out why we didn't catch #1478 in CI. Creating an issue to ensure we don't forget!

I looks like Travis scripts only worry about the last command for the error code. travis-ci/travis-ci#1066 .

cibuildwheel/.travis.yml

Lines 55 to 62 in 5e15bb2

	script: |
	# travis_wait disable the output while waiting
	# use the same kind of tricks as in multibuild
	(while true; do echo "travis_keep_alive"; sleep 300; done) &
	SPINNER_PID=$!
	disown
	$PYTHON ./bin/run_tests.py
	kill -9 ${SPINNER_PID}

A set -o errexit should do the trick. I wonder if that will work on Windows too, do they run a POSIX shell on all platforms?

this is still an issue on TravisCI as the tests are failing but the workflow isn't...

this was fixed in #1970
