Review request for Plasma.


Description
-------

    Check if referenced objects are valid
    
    This kills two ReferenceErrors I'm seeing when using ListItems inside
    VisualItemModels (in this case, there's no view and visual parent
    attached on creation).


Diffs

Testing
-------

Thanks,

Sebastian Kügler
