    passwords-view: fix the Clear All action
    
    Apparently people don't try to delete all their passwords very often,
    because this has been broken for the past year and nobody noticed until
    now. Whatever. The dialog is no longer a GtkWindow so we just have to
    find the parent window instead.
    
    Fixes #1570
