Updating container does not update node
I followed the Synology DSM [update procedure](https://github.com/oznu/docker-homebridge/wiki/Homebridge-on-Synology#updating-homebridge) precisely several times now but never was able to get rid of this error message:

```
[2019-1-26 13:02:50] [Hue] homebridge-hue v0.11.11, node v8.12.0, homebridge v0.4.45
[2019-1-26 13:02:50] [Hue] warning: not using recommended node version v10.15.0 LTS
```

Unfortunately, it seems that node is never updated like it should. What can I do?

Many thanks!
