Unable to define fragments in loader

[laverdet]

When using graphql-tag/loader under Webpack, the returned results are surprising when working directly with fragments in processed files.

I put together a full reproduction here:
https://github.com/laverdet/graphql-issue

If you clone the repository and run npm install; npm start you will see the following output:

query Hello {
  ...Fragment
}

query Query {
  id
}

fragment Fragment on Model {
  id
}

It is unexpected that query Query would end up in the output considering it is not referenced at all.
