[autostart] autostart on Windows is removed after one boot

[joshsharp]

Hi, I'm sorry but this is going to be a very vague bug report as I'm having trouble understanding what's happening.

I have been using autostart for a while with no issues and was using the dev branch as instructed, then started getting this issue. I moved to depending on v1 branch but the issue persisted.

I've installed the plugin as described in the readme:

let app = tauri::Builder::default()
    // snip lots of setup
    .plugin(tauri_plugin_autostart::init(
        MacosLauncher::LaunchAgent,
        Some(vec!["--quiet"]),
    ))
    .build(context)
    .expect("error while building tauri application");

To turn it on, I call enable() in Javascript:

import { enable, isEnabled, disable } from "tauri-plugin-autostart-api";

// later...
await enable();

Essentially what's happening is that upon calling enable() from the exposed JS module the registry entry is added on Windows successfully in the correct location and upon next boot the app is successfully launched at startup. However, somehow (upon launch of my app? upon registry of the plugin?) the Windows registry item in the HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run location is somehow removed. If enable() isn't called again, the app will fail to run on next boot.

Thanks for your help.
