YaDisk.Upload() not actaully apply argument "overwrite" about yadisk

[ivknv]

The overwrite parameter is not ignored, it's just that you can't overwrite folders.

This isn't really a bug, this is just how the Yandex.Disk's REST API works. Getting an error in this case makes perfect sense. You are supposed to provide the full destination path, not just the parent folder.

Expected:
No exceptions and file was uploaded to existing folder in Yandex Disk

Introducing the suggested behavior would only make the method less consistent and could lead to silent accidents (e.g. accidentally uploading into a folder instead of overwriting what was assumed to be a file).
