DBTrans只能在当前数据库中操作，不能操作后台文件

### 该问题是怎么引起的？
使用后台数据库初始化事务，调用trans.Dispose()时提示异常“Autodesk.AutoCAD.Runtime.Exception:“eNotCurrentDatabase”

### 重现步骤
            var doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Cast<Document>()
           .FirstOrDefault(doc => doc.Database.OriginalFileName == fileName);
            DBTrans trans;
            if (null != doc)
                trans = new(doc, true, true);
            else
            {
                Database _db;
                //如果存在文件，读取内容
                if (System.IO.File.Exists(fileName))
                {
                    _db = new Database(false, true);
                    _db.ReadDwgFile(fileName, FileOpenMode.OpenForReadAndWriteNoShare, true, null);
                    _db.CloseInput(true);
                }
                else
                {
                    _db = new Database(true, false);
                    _db.SaveAs(fileName, DwgVersion.AC1021);
                    _db.CloseInput(true);
                }
                trans = new(_db, true);
            }
            DBText dBText = new() { TextString = "123456", Height = 200 };
            var mds = trans.ModelSpace;
            mds.AddEntity(dBText, trans.Transaction);
            trans.Dispose();
