fix: single answer questions dont get stored with metadata

[atlj]

Summary

If a question has a single answer on create-react-native-library, we skip that question. However, due to a bug, single answer questions weren't making it to the metadata stored with new project. This PR fixes that

Test plan

A good example is the Fabric view with backward compat. This option had a single language setting kotlin and objective c. To test this PR, you can create a new project with these options and make sure the language is getting stored properly.
