Previously, only some calls to ApiExtended.CreateAsync() would prompt users to login if necessary. Other calls would only work if the account already had a valid identity, and they would throw exceptions otherwise.
Changed ApiExtended so that the UI registers a static ILoginChoiceEager factory delegate that ApiExtended will use in the event that a login is required.
