Testing secured endpoints

We're now ready to test our user API endpoints. The first thing we should do is create a new test file for testing these. So let's go:

$ touch tests/unit/server/user.test.js

Let's then copy all the required modules from the top of the items test file as we'll need most of these in the users test file, too.

We'll make a few alternations, though; let's require the User model rather than the Item one.
