Message: [state() called before manage() for tauri_plugin_global_shortcut::GlobalShortcut<tauri_runtime_wry::Wry<tauri::EventLoopMessage>>]
```

The root cause is that, in a Tauri application, before you can access a piece of
managed state with the .state() method, you must first register it with Tauri
using .manage(). When a user reigsters hotkey for an extension,
initializing extensions will invoke the .state() method, at that point,
.manage() hasn't been called.

The fix is simple, we simply call .manage() earlies (invoked by our
`shortcut::enable_shortcut(app)` function).
