Extended my previous contribution to @hollo tonight with some tests for the `GET /api/v1/accounts/verify_credentials` route:

There's some magic going on here, but I'm pretty happy with the results.

Though, node.js's test runner seems really slow at times and I've no idea why, like some of these are taking 1-4 seconds, whereas other tests are 54ms. I've tried instrumenting the code to find slownesses and I can't, everything's taking only milliseconds.
