epiphany-add: Always restart the browser service

The browser is meant to be the only UI for the running device. So
stopping it would make little sense. epiphany, even in app mode, doesn't
hide the window controls - including the window closing button. If that
is triggered by mistake, systemd would restart it unconditionally.
