Stop reading advanced logs on ConnectionError (#5900)

* Stop reading advanced logs on ConnectionError

If the client side connection closes with a `ConnectionError`, stop
reading the advanced logs.

This is very similar to ClientConnectionResetError which is easily
reproducable by having a log open and following in the browser and
then restaring Home Assistant. So far I wans't able to artificaially
reproduce the ConnectionError, but there are quite some reports on
Sentry so it seems to happen in real world.

* Warn on ConnectionError
