fix(alembic): merge 双 head(meituan_coupon_image_meta + 4dc2af7ebe74)

#71 的 meituan_coupon_image_meta 与并行合入的 4dc2af7ebe74(device_65/comparison_token 合并) 形成两个 alembic head,`alembic upgrade head` 报 "Multiple head revisions"。加一个空 merge 迁移把两 head 合一,恢复 upgrade head 单 head 可用(线上已临时用 upgrade heads 应用两条)。
