Error: Cannot find module 'shell'

[macmedia]

Environment

Mac OS 10.13.3 (High Sierra)
Electron - v1.8.4
Node - v9.8.0
nom - v5.6.0
Git-it - v4.3.3 (master)

Problem

When running the pre-built (v4.3.3 Mac-X64) or building it myself, I was getting a
Uncaught Exception:Error: Cannot find module 'shell'

Click on Help -> Repository menu and the error pops up.

I updated the darwin-menu.js to use shell.openExternal like its done with Help -> Open Issue. This has corrected the error and the url opens.

Error Message

Uncaught Exception:
