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

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

Moved the dereference after error handling for null check.

On UpdatePeer event and AddPeer  methods there is missing implementation for updating or adding avatar and extrInfo of a peer.

Peers are able to join on the TTL expired room.

But room entry not created on the redis only peers entry is created.

Checking the room entry exist on the redis if not creating one.

This kind of approach used on old version, removed on the latest releases.
