fix: peers avatar and extraInfo not updating on redis (#599)

* fix: peers avatar and extraInfo not updating on redis

Everywhere we have type declaration and usage for avatar and extraInfo for peer. But not set on redis while creating peers.

* fix: SA5011 lint error on room_signal file

Before pinfo null check routines returning error sid and uid are dereferenced.

Moved the dereference after error handling for null check.
