[chromecast] Fix constant disconnections (#14105)

Browse Source 
When ipv6 is configured on the network, Chromecast devices will randomly
return ipv4 and/or multiple ipv6 addresses during mdns discovery.
This would trigger a thingUpdated call which will call dispose/initialize,
causing the thing to go offline/online.
