    list-view: Make star cell blank and inert on dummy row
    
    If org.gnome.nautilus.list-view use-tree-view is TRUE, folders can
    be expanded, which creates a dummy row to display the "Loading" label.
    
    The code to display the correct star icon assumes each row represents a
    file, but the dummy row breaks this assumption, crashing nautilus when
    checking if the NULL file is starred or unstarred.
    
    Instead, don't set a star icon unless the row represents a file. Also,
    do nothing if the cell is clicked on a dummy row.
    
    Fixes: #105
