Both the "Starred" and "Network" locations are internal to nautilus and not exposed to gvfs. We can still support them by opening them explicitly in nautilus, so add corresponding places if nautilus is installed and set up as default file manager. After this change, the list of places should be consistent with the sidebar in the file manager again.
