fix: immediately mark the workspace as deleting

- workspace status is usually updated every 5 seconds by the polling loop.
- that's a bit problematic because when we delete a workspace we have to wait a
  couple of seconds until we have some visual feedback.
- with this patch we force the workspace status to be in "deleting" if the REST api call
  was succesfull.
