Support RollbackUnlessCommit

[flycash]

In order to make handle transaction manually more easily, I provide a new API named RollbackUnlessCommit, it was inspired by gorm v1. And I think it could reduce such code:

if err != nil {
   tx.Rollback()
   return err
}

I forget to call Rollback several times when I used beego Orm.
Now, I can write code looks like:

tx := o.Begin()
defer tx.RollbackUnlessCommit()

Close #4428
