[Urgent] User messages shown to wrong user


#1

[Note: ticket is probably related to [Urgent] Users become logged in to another user where users log in as the wrong user]

Summary

Users are seeing messages that people sent to someone else.

Steps to reproduce

Mattermost Version: 5.3.1
Database Schema Version: 5.3.0
Database: postgres

User A logs in, suddenly becomes User C instead.
User A sent message to User B.
User B sees this message under User C’s direct messages, but in the chat itself it still shows as from User A.
User B replies to User C with a test message.
User C sees the test message AND the original message which User A sent to User B.

Expected behavior

Message should only go to users who they were sent to.

Observed behavior
