fix form switch changed callback

Here this example showed garbage when the switch widget was changed ```sh yad --form --field=switch:SW TRUE --field=check:CHK TRUE --changed-action='echo 3:' --field=changes ``` To fix this issue I changed the callback according to the gobject signature https://docs.gtk.org/gobject/signal.Object.notify.html.
