eslint broken since migrating torbutton

When I try and run eslint now I get errors like

Error: Failed to load plugin 'mozilla' declared in '.eslintrc.js': Could not load globals from file /.../tor-browser/toolkit/torproject/torbutton/chrome/content/tor-circuit-display.js: Error: ENOENT: no such file or directory, open '/.../tor-browser/toolkit/torproject/torbutton/chrome/content/tor-circuit-display.js'

I think this was caused by !466 (merged)
