Specifies exact version of qunitjs.

[tyleryasaka]

qunitjs is a dependency of ember-cli-qunit. By not explicitly stating the version we want, we get the latest 2.x version. The problem is that anything after 2.2.1 breaks our tests at the moment.

Funny observation: It is always 38 failing cases and they all involve explicitly calling click() on an element.

Thank you for this. I'll merge this, but it would be nice to find the exact cause of the failures.

@miguelcobain it's probably related to this issue in ember-cli-qunit (ember-cli/ember-cli-qunit#162), which was an effect of an API change in QUnit (qunitjs/qunit#1145) which broke a lot of Ember projects.

I also thought that was it, but it seems explicitly setting qunitjs to 2.3.2 (clearing out node_modules and npm install) still fails on the 38 cases. The error message is slightly different (Assertion occured after test had finished vs. Assertion after the final...) which comes from https://github.com/qunitjs/qunit/blob/master/src/test.js#L375.
