Error when the zip contains a folder:

When "Extract here..." or "Extract to..." the output folder must be the folder: <selected folder>/<archive base name> For instance when extracting foo.zip in /tmp the zip content will be in /tmp/foo (i.e. NOT in tmp).

Problem: the /files/_unzip REST point is not accessible to non-administrator users.
