Summary: - Moved /test/client and /test/common to core. - Moved two files (CircularArray and RecentItems) from app/common to core/app/common. - Moved resetOrg test to gen-server. - `testrun.sh` is now invoking common and client test from core. - Added missing packages to core's package.json (and revealed underscore as it is used in the main app). - Removed Coord.js as it is not used anywhere. Test Plan: Existing tests Reviewers: paulfitz Reviewed By: paulfitz Subscribers: paulfitz Differential Revision: https://phab.getgrist.com/D3590
