Fix Java 11 issue where the order of methods returned in AssignmentEndpoint subclasses returned wrong method for determining the mapping of an assignment. Now we walk over all methods until we find one which has for example a @GetMapping with AttackResult or ResponseEntity<AttackResult as return type. If no such method is found an exception is thrown
