modules_k/pua: Temporary dialogs did not contain all of the required fields.

- Temporary dialogs are created when a SUBSCRIBE is sent to handle the timing
  issue that means that NOTIFYs can be processed before 200 OKs (the real
  dialog is created on 200 OK).
- Not every required field was filled in for the temporary dialogs so dialog
  searches were failing and duplicate dialogs created.
