Cache control hints doesn't work on extended types on federated schemas

### Packages
```
{
"@apollo/federation": "^0.11.0",
"apollo-server": "^2.9.9",
"apollo-server-plugin-response-cache": "^0.3.5"
}
```

### Issue

It seems like cache control hints doesn't work on extended types on federated schemas

Having these schemas in two different federated services

```graphql
# This is defined on the users service
type User @key(fields: "id") {
id: ID!
username: String
}
extend type Query {
me: User @cacheControl(maxAge: 60)
}
```

```graphql
# This is defined on the organizations service
type Organization @key(fields: "id") {
id: ID!
name: String
}
extend type User @key(fields: "id") {
id: ID! @external
currentOrg: Organization @cacheControl(maxAge: 60)
}
extend type Query {
currentOrg: Organization
}
```

and running this query

```graphql
query {
me {
id
username
currentOrg {
id
name
}
}
}
```

results on the `me` query response being cached but not the one from `me.currentOrg`.

I also tried setting `info.cacheControl.setCacheHint({ maxAge: 60 })` on both resolvers and the result is the same.

### Expected behavior

The response from `me` and `me.CurrentOrg` are cached

### Actual behavior

Only the response from `me` is cached

### Steps to reproduce

I created a repo that reproduces this behavior here https://github.com/gnkz/apollo-federation-cache

Start by running the reproduction repository at https://github.com/gnkz/apollo-federation with the listed @apollo/federation, apollo-server, and apollo-server-plugin-response-cache versions. Compare cache-control behavior for me and me.currentOrg, including resolver hints; done when both responses are cached across the federated schema.
