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.

从 launches.js 开始，将正常工作的内联查询与基于片段的 GET_LAUNCHES 查询进行比较，然后针对 GraphQL 服务器重现缺失的请求。当基于片段的查询发送 POST 请求并将发射数据加载到组件中时，即表示完成。
