web: TacComponents: OverTemperatureNotification: fix note on disconnect

hnez · hnez · commit d8c419a29377 · 2024-01-11T12:25:22.000+01:00
The onConnectionLost handler in mqtt.ts sets all subscribed topics to
`undefined` on disconnect, so the `null` check never triggered.
Check for `undefined` instead.
