    Fix assertion failed crash
    
    Fix "assertion failed: (last_slash != NULL)" crash while navigating the
    left tree view, fixed by having the model for the right list view emit
    all the row deleted signals before deleting any of its data.
    
    Fixes https://bugzilla.gnome.org/show_bug.cgi?id=670586
