    gio: Fix querying of thumbnail attributes other than thumbnail::path
    
    The thumbnail attributes would previously only be set if thumbnail::path
    was included in the query — so querying for just thumbnail::is-valid
    would return no results.
    
    This fixes the behaviour of
        gio info -a thumbnail::is-valid ./some-file.png
    vs
        gio info -a thumbnail ./some-file.png
    
    The first command would previously list nothing. The second would
    previously list a thumbnail::path and thumbnail::is-valid.
