Describe the bug

When using inlineFragmentTypes: 'combine' and mergeFragmentTypes: true together, if I create a fragment on an interface and then use it, the types that are generated are invalid.

It's trying to reference the types that are generated without mergeFragmentTypes i.e. UserDetails_UserWithEmail_Fragment when they have been merged into UserDetailsFragment so it's now invalid

Steps to Reproduce the Bug or Issue

1. Create a fragment on an interface
2. Use it in two different queries for two different types
3. Run codegen with inlineFragmentTypes: 'combine' and mergeFragmentTypes: true

Expected behavior

I would expect the generated types to reference the merged fragment types i.e. UserDetailsFragment not UserDetails_UserWithEmail_Fragment
