[DESK] Fix screensaver preview after calling its settings (#4921)

Fix a bug when after closing the settings window for a screensaver,
    the preview for it wouldn't restart.

- Keep waiting for messages from the settings window while it's open
    - Fix leaking two handles to avoid creating zombie processes
