Fixed a bug where an error fetching past events on subscriber initialisation would prevent receiving any future events.The API still reports the error in the console, records it in the LearnosityEvents.errors list and sends it to the errorListener if specified, but now continues to send subscribe requests to retrieve new events and deliver them to the application.
Fixed the messages reported on backend errors. Previously, raw backend error responses were reported verbatim in the console. An additional error message is now reported, if available, giving more context about what the error means for the API (e.g., fatal or not). This does not impact what gets recorded (i.e, the error only) in LearnosityEvents.errors nor sent to the errorListener.
Fixed a bug where requests denied with 4xx HTTP errors would be retried in a tight loop. This prevents overloading the backend with a lot of known-incorrect requests. As before, the request is passed to the caller's errorListener, allowing it to be informed about the issue and take further corrective action if needed.

Fixed a bug where calling Try Again would consistently return options in the same order across refreshes on the following Question types: Multiple Choice, Choice Matrix (standard and inline), Classification, Cloze Association, Association and Image Cloze Association.
