Gorm Sqlite 在执行AutoMigration时候，如果tag中指定了索引名称，会导致不同表执行生成同样的索引名称然后报错

example: https://github.com/go-gorm/playground/pull/782

package main

type Order struct {
    ID      uint64 `gorm:"column:id;type:bigint unsigned;primaryKey;autoIncrement:true"`
    UserID  uint64 `gorm:"column:user_id;type:bigint unsigned;not null;uniqueIndex:unique_user,priority:1;"`
    Product string `gorm:"column:product;type:varchar(63);not null;"`
}

type User struct {
    ID      uint64 `gorm:"column:id;type:bigint unsigned;primaryKey;autoIncrement:true"`
    UserID  uint64 `gorm:"column:user_id;type:bigint unsigned;not null;uniqueIndex:unique_user,priority:1;"`
    Name string `gorm:"column:product;type:varchar(63);not null;"`
}

func main() {
    db, err := gorm.Open(sqlite.Open("gormtest.db"), &gorm.Config{})
    if err != nil {
        panic(errors.Wrapf(err, "failed to connect to database"))
    }

db.AutoMigrate(&Order{},&User{})
}

SQLERROR: SQL error or missing database (index unique_user already exists)

sqlite驱动需要在生成索引名称时候自动添加表前缀作为索引名称区别
