Return to loading config.yaml for testing
Return to loading config.yaml for testing

I84094d1713af89f908e32fefaead48c548e87cb7 changed test/utils/server.js
to load config.test.yaml rather than config.yaml when starting the test
server.  The current deploy repo build is failing in CI and this might be
why.
