Default Electron showing after upgrading from 19.47.1 to 19.53.0

• Version: Tested on 19.47.1, 19.53.0, and 20.0.8

• Target: Linux (deb, AppImage)

This issue was first discussed in #2577 (comment)

The problem is that my build suddenly started showing the default Electron icon after upgrading electron-builder from from 19.47.1 to 19.53.0 (also happens in 20.0.8). My guess is that it has something to do with the Golang icon refactor that was done around the same time.

I created a Gist with the debug build output (from 20.0.8) and highlighted what I think are the relevant lines: https://gist.github.com/gschier/34d7757010e4908e16ad8cad9facc9a7#file-electron-builder-debug-txt-L121-L125

It seems like it's not even trying to locate /home/gschier/Desktop/sf_insomnia/packages/insomnia-app/build/icon.icns and falling back to the default Electron icons.

Thoughts? Let me know if there's anything else I can provide.
