ObservedV2 中 Trace 装饰的属性使用了@Columns无效

[tyyax]

在@ObservedV2装饰的类中的@trace数据不能被列检测到。
例如：

`@ObservedV2
@entity({
tableName: ConversationModel.tabName,
index: [{
name: "ai_conversation_conversation", columnName: ["conversation_id", "tittle"]
}]
})
export class ConversationModel {
static tabName: string = "ai_conversation"

@trace
@columns({ name: "tittle", type: ColumnType.TEXT })
tittle: string = ""

@columns({ name: "last_message_time", type: ColumnType.INTEGER })
lastMessageTime: number = 0

@columns({ name: "create_time", type: ColumnType.INTEGER })
createTime: number = 0
}`

建表时tittle没有被包含在内，在modelToValuesBucket中也没有解析到tittle。
