    inspector: Stop showing settings bindings
    
    We were playing fast-and-loose with private GIO data
    when showing settings bindings in the property editor,
    and this was causing crashes.
    
    We can show this information again if GIO ever gets
    api to introspect it.
    
    Fixes: #3015
