Built-in role descriptions reset

Description:

If you would be so kind as to not keep resetting the Description of the built-in roles every time the RocketChat server reboots, that'd be great, thanks.

Steps to reproduce:

1. Start RocketChat. Login to RocketChat. Go to Permissions and change the "Description" field of the "admin" role to an empty string. Click "Save" to save your changes.
2. The role description is now empty. Hooray!
3. Restart RocketChat.

Expected behavior:

RocketChat remembers my change and leaves the built-in roles alone.

Actual behavior:

RocketChat decides to put the default description for the built-in roles back.

Server Setup Information:

• Version of Rocket.Chat Server: 3.7.1
• Operating System: CentOS 8
• Deployment Method: Local installation under /opt/rocketchat
• Number of Running Instances: 1
• DB Replicaset Oplog:

• MongoDB Version: v4.4.1

Client Setup Information

• Desktop App or Browser Version: 3.0.7
• Operating System: Windows 10

Additional context

I've got a feature enabled that shows the role descriptions as badges in the message window. In order to control what I see there, I'm blanking out the descriptions for the built-in roles and using custom roles for display purposes.

Relevant logs:

I don't have any. I think this might just be an issue where RocketChat mistakingly thinks that something is wrong because the Description field is empty or something.

No files, tests, or entry points are identified in the issue. Reproduce the role-description reset by clearing the built-in admin description, saving it, and restarting Rocket.Chat; done means the empty description remains unchanged after restart.
