* Middleware overhaul! - Remove unnecessary 'async' keywords from middleware functions - Ensure all middleware functions we create have names - Wrap the method contents of all async middleware functions in a try-catch+next(error) pattern * Use asyncMiddleware wrapper instead of try-catch+next(error) pattern * Remove unnecessary try-catch+next(error) pattern from context middleware
