### Electron Version

16.0.0-beta.3

### What operating system are you using?

Other Linux

### Operating System Version

Linux pop-os 5.13.0-7614-generic #&#x2060;14\~1631647151\~21.04\~930e87c-Ubuntu

### What arch are you using?

x64

### Last Known Working Electron version

15.3.0

### Expected Behavior

From the documentation for `app.getPath("userData")` (https://www.electronjs.org/docs/latest/api/app#appgetpathname):
> The directory for storing your app's configuration files, which by default it is the appData directory appended with your app's name.

So `app.getPath("userData")` in the linked gist should be `~/.config/test-electron`.

### Actual Behavior

`app.getName()` returns the correct name from package.json but `app.getPath("userData")` returns `~/.config/Electron`.

### Testcase Gist URL

https://gist.github.com/weedz/ad42b854df4e5bc411d18e48ae1c91df
