[Chess] chess/ai.test.js sometimes takes a really long time to run

[jasonharrison]

On my server: PASS games/chess/ai.test.ts (73.584s)

It seems to only happen SOMETIMES. I tried 6x times to get this to happen with yarn run test:unit --verbose games/chess/ai but could not reproduce.
I noticed this also happened on Travis:

PASS games/chess/ai.test.ts (73.061s)

https://travis-ci.com/github/freeboardgames/FreeBoardGames.org/builds/158634397

My server and Travis took almost the exact same time to run this test-- very interesting
