added_to_team websocket event is sent duplicated #19810
Description
Right now, we are sending the added*to*team websocket event twice. This is due to AddTeamMember calling AddUserToTeam and this one calling JoinUserToTeam. Both AddTeamMember and JoinUserToTeam are sending the websocket event.
The naive solution would be to remove from any of the two the websocket event. Nevertheless, I am not sure of the possible implications and possible paths.
