Invalidate addressFilter if an address is not given

In src/routers/transactions.ts and src/routers/validator.ts,
addressFilter can be truthy even if address is falsy.

The addressFilter field should be restricted by the address field.

阅读 src/routers/transactions.ts 和 src/routers/validator.ts 中对 addressFilter 的处理，重点关注其与 address 字段的关系。确认当 address 为 falsy 但 addressFilter 为 truthy 时的预期行为，然后验证两个 router 是否都根据 address 一致地限制 addressFilter。
