If the ASSERT_MIN_TS_HAS_NOT_FALLEN_OFF_OPLOG is set, a client expects to receive an `OplogQueryMinTsMissing` error if an optime has rolled off the oplog. However, after SERVER-86216, we sometimes fail to return this error. This can lead to a resharding op not failing when it should fail, which could lead the resharding op to lose data.
