Michael Bucari-Tovo f35c82d59d Change ApiExtended to always allow provide login option
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.
