Summary: This helps forcibly end mocha tests when they hang, and print out something that may help debug the situation. Also add the generated static/bundle.css file to core/.gitignore. Also, avoid using npm-packages-offline-cache when building core, by avoiding use of .yarnrc which turns it on. Test Plan: Tested manually Reviewers: paulfitz Reviewed By: paulfitz Differential Revision: https://phab.getgrist.com/D2788
