Delete some unused code in js/utils/
Review Request #8046 — Created March 9, 2016 and submitted
This change deletes some code in js/utils which is no longer necessary.
Specifically, this includes:
- The
Object.getPrototypeOf
polyfill is now included via babel's polyfill, so
we don't need to ship our own. - Backbone's
Events.once
polyfill is no longer necessary because we're on a
Backbone version that includes it. RB.FormatTimestamp
just wasn't used anymore.
Ran js-tests.
