fix: handle logout from a background thread (#20688) (#20707)

Allows AuthenticationContext.logout feature to be used from a background thread, handling the missing request by forcing the client to make an additional request. Applies the same logic used to support logout when using PUSH with websocket transport. References #11026 Co-authored-by: Marco Collovati <[email protected]>
