systemd service file should include a "Restart=always"

When the client push is configured but the service is not running, this causes permanent browser issues as the browser always tries to establish a wss connection to the push service. You can see that in the browser console.

As a side effect this also delays the connection to the signaling server in Talk when entering a chat room ... up to messages that the signaling connection does not respond in time.

I found that, when the complete server VM is started, the notify_push service can start before the database is up. That leads to an error and notify_push often does not run.

The additional command

Restart=always

in the [Service] section should restart the service in that case until the database is up and the service is running.

Maybe that should be added in the documentation (sample service file).
