Address Book example: Correctly update "Edit entry" and "Remove entry" actions
They are not updated after switching tabs. Thus they can be enabled even when no entry is selected: select an entry on the current tab and then switch to an empty tab. Emit AddressWidget::selectionChanged() signal after changing the current tab to update these actions.
