Issue introduced by [Restrict queried columns to graphql-requested
fields](https://github.com/twentyhq/twenty/pull/13246)
In this query
```ts
{
...
name
messageId
message {
id
}
}
```
`messageId` was being filtered out from the selected fields as we failed
to link it to an existing field, thus null was always returned.
`message { id }` worked because we already handled connections
correctly.
