The `SceneManager.bootScene` method will now always call `LoaderPlugin.start`, even if there are no files in the queue. This means that the Loader will always dispatch its `START` and `COMPLETE` events, even if the queue is empty because the files are already cached. You can now rely on the `START` and `COMPLETE` events to be fired, regardless, using them safely in your preload scene. Fix #5877
