Figure out why Teaspoon occasionally fails on Travis

(Usually works after restarting the build with no changes)

Debugging output below. Just as a wild guess, I'm thinking there's a race condition. spec_helper.js calls CodeTestBotApp.setupForTesting(); but it might happen that the application finishes loading before it gets there.

With the merge of #14, we're no longer using Teaspoon so this is now invalid.
