Kdesktop 984 implementation of app self restarter causing issues with (un)installer

[herve-er]

The implementation of the new App self-restarter is problematic for the installer/uninstaller. The installer/uninstaller needs to kill the app, but the self-restarter causes the app to restart immediately, which is breaking the installer/uninstall process.

Steps to Reproduce:

1. Launch kDrive App (a version with the self-restarter ie: branch develop)
2. Run the installer or uninstaller.
3. Let it attempt to kill the app.
4. Observe the app restarting immediately due to the self-restarter.

Expected Result:

The app should remain closed when the installer or uninstaller kills it, allowing the update process to complete successfully.

Task List:

• [x] Fix on Windows
• [x] Check if the issue is present on Linux
  • [x] Fix on Linux (Not concerned)
• [x] Check if the issue is present on macOS (it is)
  • [x] Fix on macOS (@ClementKunz)

[herve-er]

@ClementKunz will provide a fix for the mac uninstaller.
