DI doesn't work correctly with Reuse

[PatrykSzwer]

I have view-model that is called both through direct call to its handler, but it's also part of other view-model as Reusein Json:

  "Editor": {
    "$": {
      "Reuse": "BlendingEditor.Composition.ViewModels.CompositionEditorPopup"
    }

This view-model has service included trough Dependency Injection:

 		private IFileSystemService fileSystemService;
        public CompositionEditorPopup(ICurrentUserProvider<User> currentUserProvider, IFileSystemService fileSystemService)
        {
            this.fileSystemService = fileSystemService;
        }

And when one of this view-model handlers is called trough this other view-model with Reuse, fileSystemService is null. I'm not sure if I'm missing something or/and it should be like that, or It's a bug.

Unfortunately, this is expected behavior right now, to get it fixed, Starcounter.Startup would have to be integrated into XSON.
