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.
