Fix parsing of GraphQL fragments in editor views

[execveat]

Editor views don't handle GraphQL fragments well. They actually can get lost completely right now.

This has been fixed along the way I guess. Tested by creating request in Repeater and pasting the following query to GraphQL tab:

fragment UserInfo on User {
  id
  name
  age
}

fragment AddressInfo on Address {
  street
  city
  country
}

query GetUser($id: ID!) {
  user(id: $id) {
    ...UserInfo
    address {
      ...AddressInfo
    }
  }
}

After that, go to Pretty/Raw and edit something - come back to GraphQL and observe that the query is fine. Tried playing with it but didn't find any parsing issues. I guess it got fixed by a random commit in GQLSpection.
