Fix storage query

[ccanos]

This typeorm query: was turned into this:

I have just removed the useless selected columns to retrieve only the SUM(size).

---

Has been difficult to reproduce in localhost, because we don't have ONLY_FULL_GROUP_BY enabled in our local mysql container.

I have tried to enable it with this command:

SET session sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION'

but that was not enough - not sure why - SELECT @@sql_mode; was still the same.

• I have added a volume to quickstart-services.yml: - ./mysql-custom-config:/etc/mysql/conf.d
• Created a file my.conf in server/mysql-custom-config
• Added this lines:

  [mysqld]
  sql_mode = "STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION,ONLY_FULL_GROUP_BY"

The other values STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION are the default ones for our local mysql server, but I would like to run SELECT @@sql_mode; on all the environments and make sure that we configure all the environments the same way including local.
