Issue with Windows NSIS Uninstallation Logic

[ys928]

I have encountered an issue with the NSIS uninstallation logic in the electron-builder. When using custom uninstallation commands, the current logic deletes all files before executing the custom uninstallation commands. This results in my uninstallation script being deleted before it can be executed.

Steps to Reproduce:

Create a custom uninstallation script.

Add the custom script to the NSIS uninstallation process.

Run the uninstallation process.

Expected Behavior: The custom uninstallation script should be executed before all files are deleted.

Actual Behavior: All files, including the custom uninstallation script, are deleted before the custom uninstallation commands are executed.

File Path: uninstaller.nsh

After my testing, it was ok to move these three lines of script to line 144
