Fragments-only set of files are not supported

[wasd171]

Hi,

When trying to generate types for a set of files that only contains fragments, apollo client:codegen fails with

Error: No document sets found to generate code for.

I suppose that it's related to the following line in apollo/lib/commands/client/codegen.js:

if (!operations.length) {
  throw new Error("No document sets found to generate code for.");
}

As a workaround I can add any query and then codegen works

I'm also getting this error and my project has various queries and mutations:

Was able to generate with version 1.9.2 (files/schema attached)

but with version 2.0.17 I get the error:
✔ Loading Apollo Project
✖ Generating query files with 'typescript' target
→ No document sets found to generate code for.
Error: No document sets found to generate code for.
