[BUGFIX] Workspace preview uncheck all button

In workspace frontend preview, clicking the "Send to stage"
button renders a modal to select mail recipients to notify
recipients. The two "Check all" / "Uncheck all" buttons
don't work since the click events are not registered in
preview mode. The patch adds them.
