Update CircleCI to pass tenon.io test

[Julian Norton]

What's the current situation?

CircleCI unit testing is failing on circleCI, but passing locally.

  1) Weather10kb app should pass tenon.io accessibility tests:
     Uncaught TypeError: Cannot read property 'code' of null
      at tenon.submit (test/integration/app.test.js:46:23)
      at Request.request.post [as _callback] (src/modules/TenonRequest.js:15:662)
      at Request.self.callback (node_modules/request/request.js:186:22)
      at Request.<anonymous> (node_modules/request/request.js:1163:10)
      at IncomingMessage.<anonymous> (node_modules/request/request.js:1085:12)
      at endReadableNT (_stream_readable.js:1101:12)
      at process._tickCallback (internal/process/next_tick.js:152:19)

What do you recommend?

Update or investigate the current tenon.io in /unit/test
