复制嵌套目录时，出现重复任务及结果

[1-1-2]

Please make sure of the following things

• I have read the documentation.
• I'm sure there are no duplicate issues or discussions.
• I'm sure it's due to alist and not something else(such as Dependencies or Operational).
• I'm sure I'm using the latest version

Alist Version / Alist 版本

v3.0.0-rc.0

Source(Webdav(onedrive)): tree 测试

└─folderA
        fileA - 副本.txt
        fileA.txt

Target(alipyunpan): rclone tree alist:ALI/测试/

├── fileB.txt
├── folderA
│   ├── fileA - 副本.txt
│   └── fileA.txt
└── folderA
    ├── fileA - 副本.txt
    └── fileA.txt

2 directories, 5 files

发现两个问题：

1. folderA 被复制了两遍，详见日志中截图。
2. 同名目录中有一个 folderA 在客户端看是空的，但是在 alist 中两个文件夹内容是一致的，估计被链接到了同一个目录下？不过考虑在GUI下是不允许生成同名目录的，不知道这算不算一个没啥搞头的鸡肋BUG？
