[Bug] admin/info route renders error loading pages for "user" role users

[siva2204]

Description:

admin/info route for "user" roles renders error loading pages instead of "you are not authorized to view this page".

Steps to reproduce:

1. login as "user" role user
2. navigate to http://x.x.x/admin/info

Expected behavior:

the response must be you are not authorized to view this page

Actual behavior:

Server Setup Information:

• Version of Rocket.Chat Server: 3.13.0-develop
• Operating System: linux
• Deployment Method: tar
• Number of Running Instances: 1
• DB Replicaset Oplog: Enabled
• NodeJS Version: 12.18.4 - x64
• MongoDB Version: 4.2.8

Client Setup Information

• Desktop App or Browser Version: 88.0.4324.182
• Operating System: Ubuntu 20.04

Additional context

the actual behaviour should only happen if there's an error while getting responses but the API throws an error for the "user" role type which has been caught by the side effect to re-render the component.

I'm working on that :)

there's no need to run side effects(use effect) if the user role is "user"

@siva2204 #21218 solves this issue.

@yash-rajpal according to your pr whether a user is authorized or not, it will request server for statistics and calls method instances/get, where the server will throw an error for that method and bad request for API call (check your serverlog & devtools), if user role is "user" which gets catched and component renders again unwantedly. my pr #21221 solves this.
