New Folder woes with Dolphin, Dataloss with MTP and SiriKali

### Describe the bug
When creating a folder over sftp, it isnt "real" before another file is created inside of it.

This makes you get permission denied errors when trying to move a file or folder into it.

On some platforms it silently fails, and a move turns into loss of data.

Creating a file (like text file) is not a problem, and as long as you do that, you can move files and folders just fine.

I've had this happen with sshfs on linux and siriKali on windows

### To Reproduce
* Create a folder
* Move files into it, either from inside the volume, but can also happen from the outside

### Expected behavior
An empty folder should actually be created.

## Log

Just a bunch of ENOENTs on the path which does not exist yet.
