v2: content of App.js and App.d.ts are keep changing

[kybin]

If I don't add/remove my App's methods, their content shouldn't be changed
but it seems like their method order is keep changed whenever Wails rebuilds the app.
Which is cumbersome especially when with git.

Make them sorted in alphabetical order would be better.
