Workspace manager doesn't look elegant if the file manager doesn't handle the desktop

[Barneedhar]

When the file manager handles the desktop, clicking on the workspace switcher would colour workspaces that have an active window in it. And an orange border would be around the workspace that is currently selected.

These workspace decorations aren't available if the file manager has been disabled from handling the desktop.
