### What
When using the `Restore as draft` action from the version view, the
restored document incorrectly appears as `published` in the API. This
issue was reported by a client.
### Why
In the `restoreVersion` operation, the document is updated via
`db.updateOne` (line 265). The update passes along the status stored in
the version being restored but does not respect the `draft` query
parameter.
### How
Ensures that the result status is explicitly set to `draft` when the
`draft` argument is `true`.
