E11000 duplicate key errors

Description:

I see duplicate errors in logs that leads to errors like Invalid room [error-invalid-room] on createDirectMessage and getRoomByTypeAndName methods.

Steps to reproduce:

1. Check logs for E11000 events per day

Expected behavior:

No duplicate errors in logs and normal works of Rocket.Chat server

Actual behavior:

E11000 errors

Server Setup Information:

• Version of Rocket.Chat Server: 4.4.0
• Operating System: CentOS7
• Deployment Method: docker
• Number of Running Instances: 12
• DB Replicaset Oplog: Enabled
• NodeJS Version: 14.18.2
• MongoDB Version: 4.2.17

Client Setup Information

• Desktop App or Browser Version: 3.5.7
• Operating System: Windows 10

Additional context

I don't know about specific impact for users from that errors, I guess users get some errors when they not expect to get them, for example when creating some chats.

Relevant logs:

Start with the reported createDirectMessage and getRoomByTypeAndName methods, then reproduce the E11000 events using the supplied server, deployment, replica-set, and multi-instance details. Trace how the duplicate room condition produces Invalid room errors; done means normal room creation and lookup without duplicate-key or related invalid-room errors.
