refs https://github.com/TryGhost/Toolbox/issues/138 - Having the "ghost" alias only added cognitive load when reading through the test code and didn't provide any additional value. Removed the pattern to keep things simpler and more explicit
refs: https://github.com/TryGhost/Team/issues/856 refs: https://github.com/TryGhost/Team/issues/756 - The .test.js extension is better than _spec.js as it's more obvious that it's an extension - It also meaans we can use the --extension parameter in mocha, which should result in a better default behaviour for `yarn test` - It also highlights that some of our tests were named incorrectly and were not (and still will not be) run (see https://github.com/TryGhost/Team/issues/856) - Note: even with this change, `yarn test` is throwing errors, I believe because of this issue https://github.com/TryGhost/Team/issues/756
