jsonconfig file created in subfolders

I've set up a workspace with two folders:

- backend
- frontend

_frontend_ is the ember project. I added _./vscode/ember.json_ in the workspace with:

```
{
appPath: './frontend'
}
```

Workspace looks like:

```
{
"folders": [
{
"name": "Rails Backend",
"path": "backend"
},
{
"name": "Ember Frontend",
"path": "frontend"
}
],
"settings": {}
}
```

But when the project does it's setup, I'm ending up with _backend/jsonconfig.json_ as well as _frontend/jsonconfig.json_. is this expected behavior at this time?
