[TIMOB-26266] LiveView: Socket error shown when session is terminated / restarted

I do not have a 100 % reproducible case so far, but it seems like if I kill a LiveView session, e.g. to recompile the asset catalog manually (TIMOB-26265), an error screen is presented, indicating that the socket connection broke up. This is bad UX and should be validated. *EDIT*: This can be reproduced when switching from iOS to Android in Atom with LiveView enabled. It may be an Atom-plugin error where we need to kill the server on-stop.
