Check what do we need to do with the duplicated users
We have the no-duplicated users in Postgresql and that's fine. However, we have users with the same email and different username. The above is not correct for the new schema because each single user should have a unique email. We have condensed in this Google sheet all the duplicated records, the idea with this task is to provide what do we need to do for every single user. There will be easier cases than others, the idea with this task is to track the actions we will perform to get one record by each duplicated user.
