Fix status bar message showing saved when saving failed

Resolves the following issues:

- For the first time you save a .blend file, there was no feedback.
- If the file fails to save (eg "No space left on device") the status
  bar message replaces the error with an invalid "Saved" message.

  While there is a popup, the user may cancel it with mouse motion
  and be left with the status bar message saying the file saved.
