Benjamin Otte 2e7fcc24ac a11y: Redo cell update function
1) always emit signals
   Previously, newly constructed cells would be told to not emit events.
   However, we can ensure that nothing is connected to the signals, so
   they will not actually emit anything.
2) don't return anything
   The return value is unused anyway.
