Fix missing sinon lib

As original sinon.js from bower (https://github.com/blittle/sinon.js/)
is not availble any more,
and official release of sinonjs/sinon doesn't support bower for v1.17.1,
we decided to import standalone js file from:
https://github.com/Polymer/sinon.js

Keep the name as `sinonjs` as thats required by wct:
https://github.com/Polymer/web-component-tester/blob/master/browser.js#L223
