This reverts commit 7217dcb67a.
https://meta.discourse.org/t/failed-to-bootstrap-due-to-out-of-memory-killer/188141/18?u=osama
Precompiling test_helper.js is so expensive that it can make bootstrap
fail on servers with limited resources (2GB RAM). We will find another
way that doesn't require much resources.
