synchronous – specifically, a lot of tests assume the last call to
`app.advanceReadiness()` or `app.reset()` will result in a new instance
being fully-booted when the current runloop completes.
We would like new code (like the `visit` API) to stop making this
assumption, so we created the asynchronous version above that returns a
promise. But until we have migrated all the code, we would have to expose
this method for use *internally* in places where we need to boot an instance
synchronously.
