fix: possible nil player in game events on rare occasion

Make sure to create/update players in gameState (`playersByEntityID`, `playersByUserID`) on connection status changes.
Sometimes players raw info are not available on controller entity creation so it would result in missing players in `gameState.playersByUserID`.
It may be related to player disconnection as the affected player got disconnected at the beginning of the demo.
