    connection-editor: fix wired 802-1x secrets saving
    
    In case of wired 802-1x connection a temporary connection object is used,
    but since NM commit 6a19e68a7d856629600655a076b0cea4be346799
    secrets are cleared when the object is destroyed.
    So duplicate 802-1x settings instead of using g_object_ref().
