ui: Fixup KV folder creation then further creation within that folder (#12081)

The fix here is two fold:

- We shouldn't be providing the DataSource (which loads the data) with an id when we are creating from within a folder (in the buggy code we are providing the parentKey of the new KV you are creating)
- Being able to provide an empty id to the DataSource/KV repository and that repository responding with a newly created object is more towards the "new way of doing forms", therefore the corresponding code to return a newly created ember-data object. As we changed the actual bug in point 1 here, we need to make sure the repository responds with an empty object when the request id is empty.
