Fix for single file VFS servers

Browse Source 
The VFS server does not support file-system with one single-file plugin
providing the root. This is because the "leaf_path" is not universally
implemented to handle the path "/". This fix is simply to skip a
"leaf_path" check when opening the path "/".
