input-name: Ignore non-Mutation fields.

[henryqdineen]

Related #75, which we also ran into.

This PR updates the input-name rule so it will ignore any fields that aren't on the Mutation type. This assumes that the schema is using the default Mutation type name. If we want to support a custom mutation type name we could add it as an option or alternatively parse for the schema { mutation: MyMutationRootType }

Thanks!
