app-update.yml not generated (MAC zip + pkg)

[iwd-sys]

electron-builder: 19.56.0
electron-updater: 2.20.1

Target: mac ( zip + pkg)

Hi,

Thanks for fixing the issue #2313.
Now the file latest-mac.yml is generated but app-update.yml is not.

As a result, the auto-update system can't work and the following error is thrown:

[2018-01-31 11:50:50.445] [info] Checking for update
[2018-01-31 11:50:50.448] [error] Error: Error: ENOENT: no such file or directory, open 'My App.app/Contents/Resources/app-update.yml'

I forgot to mention in the issue that I have to remove this condition in my build job to have the app-update.yml.

Thank you
