Drag N Dropping a file onto a disk that is not mounted makes the file disappear

### What Happened?

Well, it's rather simple to reproduce. the only thing that is going to happen is that the file will disappear from its original location without being copied over to the destination. I ran `grep -Rnw' to search for it but it's gone

### Steps to Reproduce

1.get a usb or whatever
2. try to drag and drop a file into it when it's still not mounted (eg. there's no "used space" bar under the name of the usb on the sidemenu)

### Expected Behavior

I would expect it to either make the operation fail completely, or (what most FMs do nowadays I think) mount the target disk automatically and then copy the file over

### OS Version

7.x (Horus)

### Software Version

Latest release (I have run all updates)

### Log Output

```shell
don't have any, I might be able to send them tomorrow
```

### Hardware Info

I don't think this has much influence over the files app but..
it's a laptop with an i5-13500H, running the latest i915 drivers shipped by default I guess.
