This looks okay but I don't really understand what this is changing - could you put a few words about how this is fixing the tests? I wanna just make sure it's not hiding legitimate failures.

The change in setup means that calls in different tests to Director::forceWWW() and Director::forceSSL() don't carry over to other tests. They get reset between tests because setup() is run directly before each test.

The change in testRequestFilterInDirectorTest() is directly updating the middlewares in the Director singleton. Previously it was updating Injector so that (I think) when the Director singleton was instantiated for the first time it use the middlewares in config. I think what may have been happening is that something in one of the kitchen-sink modules was instantiating Director before the change in config.

In both of these instances, these tests do no fail on installer, only recipe-kitchen-sink. I wish I had more insight into why exactly this is happening, though I was unable to work out what was causing this.
