[GuillaumeCisco]

This Pr works with:

• forest-express
• forest-admin
• forest-admin-server

How to test?

Please follow in the right order theses steps, as there is still an issue with the forestadmin-server update

1. Switch to the fix-primary-foreign-key-to-primary-key on every projects
2. Launch forestadmin-server and forestadmin
3. In the forest-express project, run yarn build:watch
4. In the forest-express-sequelize, run yarn link forest-express, then yarn build:watch
5. Create a postgresql database with this dump:

create table if not exists customer
(
	id serial not null
		constraint customer_pk
			primary key,
	name varchar not null
);

create unique index if not exists customer_id_uindex
	on customer (id);

create table if not exists picture
(
	name varchar not null,
	customer_id integer not null
		constraint picture_pk
			primary key
		constraint picture_customer_id_fk
			references customer
);

- BE CAREFUL HERE

6. Create a project thanks to the onboarding frontend, BUT DO NOT LAUNCH IT
7. link your project to forest-express-sequelize with yarn link forest-express-sequelize
8. Launch your project
