CircleCI cache on forks

[paulmelnikow]

CircleCI caching stopped working on PRs from forks, which is to say, most of our PRs. This is resulting in failed builds on branches which change package-lock.json.

The change is a feature, which is a security change that prevents caching on forks. The change makes sense, really, though it's a bit inconvenient for us.

I'll open a PR to turn it off for now…

Should we close this issue now that you've disabled the cache in #1938 or is there some other way forward?

I’m hoping they’ll provide a way to fix this. One option is to use workspaces, as folks have noted on that thread. How about we keep it open so we remember to track that thread, and if they don’t fix it within a month, close it out?
