Fix API detail views

Previously, the event from the url was not parsed correctly for API endpoints for individual AKs, AKRooms, etc. This led to self.event being None and the queryset being empty, hence the AK, AKRoom etc. could not be found by the API. This fix makes sure, the event is loaded as part of the API initialization for all endpoints and methods.
