Type was defined more than once.

```graphql
# import Article from "./generated-schema.graphql"
type Mutation {
createArticle(data: ArticleCreateInput!): Article
deleteArticle(id: ID!): Article
}
```
and
```graphql
# import Article from "./generated-schema.graphql"
type Query {
articles(
where: ArticleWhereInput
orderBy: ArticleOrderByInput
skip: Int
after: String
before: String
first: Int
last: Int
): [Article!]!
}
```
```js
const server = new GraphQLServer({
typeDefs: ["schema/application-schema.graphql", "schema/admin-schema.graphql"],
resolvers,
context: {db: await getPrismaInstance()}
});
```

Leads to `Type "Article" was defined more than once.`

Removing imports from there and extracting them to separate file and then:

```js
typeDefs: ["schema/imports.graphql", "schema/application-schema.graphql", "schema/admin-schema.graphql"],
```
Leads to `Field articles: Couldn't find type Article in any of the schemas.`

Is there a way to handle this?

PS
No, I can't do like this:
```
# import Article, ArticleWhereInput, ArticleOrderByInput, ArticleCreateInput from "./generated-schema.graphql"
# import * from "./application-schema.graphql"
# import * from "./admin-schema.graphql"
```

I need conditional import

Start by tracing how GraphQLServer consumes typeDefs from schema/application-schema.graphql, schema/admin-schema.graphql, and schema/imports.graphql, and how the imports from generated-schema.graphql are resolved. The issue is done when conditional imports can be represented without defining Article twice or leaving the articles field unable to find Article.
