When creating a

[mklarz]

When creating a new CTF with the same name as an existing one, the bot fails to update the msg_id of the correct CTF, and it will therefore always be 0 and reactions to join the CTF will never work. We need to add a check if there is an existing CTF in the DB (even if it archived).

db["604992563199606784"].find({"name": "downunder"}).pretty()

{
	"_id" : ObjectId("5f647961fffd7de13b5efd6d"),
	"archived" : true,
	"name" : "downunder",
	//
},
{
