fix(database): 修复使用不存在的 get_all_by/get_all 方法

问题:
- CRUDBase 没有 get_all() 和 get_all_by() 方法
- 导致运行时错误: greenlet_spawn has not been called

修复:
- get_all()  get_multi(limit=100000)
- get_all_by(chat_id=x)  get_multi(chat_id=x, limit=10000)

影响文件:
- expression_learner.py: 2处修复
- person_info.py: 1处修复
- chat_stream.py: 1处修复
