Using fragment in `launches.js` stops data from being loaded.

Are you sure that presented fragment is correct? I mean it looks right but when changing from
```
const GET_LAUNCHES = gql`
query launchList($after: String) {
launches(after: $after) {
cursor
hasMore
launches {
id
isBooked
rocket {
id
name
}
mission {
name
missionPatch
}
}
}
}
`;
```
to solution with fragments:

```
export const LAUNCH_TILE_DATA = gql`
fragment LaunchTile on Launch {
__typename
id
isBooked
rocket {
id
name
}
mission {
name
missionPatch
}
}
`;

const GET_LAUNCHES = gql`
query GetLaunchList($after: String) {
launches(after: $after) {
cursor
hasMore
launches {
...LaunchTile
}
}
}
${LAUNCH_TILE_DATA}
`;
```

Data is never properly loaded into the component:

When using the fragments I can't see any `POST` request performed against my graphql server.

Inizia in launches.js confrontando la query inline funzionante con la query GET_LAUNCHES basata sui fragmenti, quindi riproduci la richiesta mancante verso il server GraphQL. Il lavoro è completato quando la query basata sui fragmenti invia una richiesta POST e i dati dei lanci vengono caricati nel componente.
