Load popper and bootstrap through a script tag to reduce flakiness on stage.

-// This is required for karma testing due to a known issue in Bootstrap-v4: https://github.com/twbs/bootstrap/pull/22888
-// The issue is that bootstrap tries to access Popper's global Popper object which is not initialized on loading
-// from the karma configuration. The next version of bootstrap (>v4.2) will solve this issue.
-// Once this is resolved, we should import bootstrap through require-config.js and main.js (for jasmine testing)
-var defineFn = require || RequireJS.require;  // eslint-disable-line global-require
-var Popper = defineFn(['common/js/vendor/popper']);
-defineFn(['common/js/vendor/bootstrap']);
