/**
 * UnknownOperatingContextController class
 *
 * - Until initialize method is called, this controller is the default
 * - AFter initialize method is called, this controller will be swapped out for the appropriate controller
 * if the operating context can be determined; otherwise this controller will continued be used
 *
 * - Why do we have this?  We don't want to dynamically import (download) all of the code in StandardController if we don't need to.
 *
 * - Only includes implementation for getAccounts and handleRedirectPromise
 *   - All other methods are will throw initialization error (because either initialize method or the factory method were not used)
 *   - This controller is necessary for React Native wrapper, server side rendering and any other scenario where we don't have a DOM
