Method logoutCleanUp request is growing up

Description:

I am using Rocket.Chat for an internal server with latest version on develop branch. I get an issue with the method logoutCleanUp. It sends a complete information of user through requests. As a result, if a user participates in many rooms, this request weights heavily. You can test it on https://open.rocket.chat.

Steps to reproduce:

1. Create an account on https://open.rocket.chat
2. Create 4 channels
3. Inspect the browser tab (F12 in Chrome), change to Network tab
4. Logout
5. Continue to create 10 or 20 or 300 channels / teams
6. Inspect the browser tab (F12 in Chrome), change to Network tab
7. Logout

Expected behavior:

Request /api/v1/method.callAnon/logoutCleanUp header content-length should not change rapidly.

Actual behavior:

Request /api/v1/method.callAnon/logoutCleanUp header content-length changes rapidly. Request payload consists of __rooms array.
