Bug Description

When there is a folder and a blob with identical name in a blob container, clone the folder will actually clone the blob.

Steps to Reproduce

Go to a blob container root dir,

1. Create directory named "folder", then upload a file to it
2. Upload a file named "folder" to the root directory
3. Clone the "folder" folder with new name "folder2"

Expected Experience

A new folder "folder2" is created.

Actual Experience

A copy of the blob "folder" is created.

Additional Context

This is the AzCopy command we use for such operation

./azcopy copy "https://account.blob.core.windows.net/container/folder/*?sasToken" "https://account.blob.core.windows.net/container/folder2?sasToken" --recursive;
