pin handlers.test_register.RegistrationTestCase.test_auto_create_auto_join_room_preset_invalid_permissions() to room version 11

A new default of room version 12 means that this test case can not
happen as is. The room creator's power level can not be moved from
infinite so will always have the permission to invite a new member
