Drop_delete does not find a file just after a drop_download

Dear all,

I would like to delete a file after having downloaded it.
But drop_delete is telling me this is not possible.

```r
drop_download(path = temp$path_display[i], overwrite = T, dtoken = token)
load(temp$name[i])

drop_upload(file = temp$name[i], path = "1.6_module3poches/Sauvegarde", dtoken = token)
drop_delete(temp$path_display[i], dtoken = token)

```

I obtain this kind of message :

```
Warning: Error in drop_delete: File not found on current path
Stack trace (innermost first):
57: drop_delete
56: observerFunc [ ... server.R#30]
1: shiny::runApp
ERROR: [on_request_read] connection reset by peer

```

Regards

Reproduce the reported sequence of drop_download, load, drop_upload, and drop_delete, beginning at server.R#30. Read the drop_download and drop_delete entry points to determine why the downloaded file is not found on the current path. Done means the same sequence deletes the file without the reported warning.
