Two source types should not be required when creating a collection
Expected behaviour
When creating a collection, you should only need to add information about source type for the content you know you will be submitting. Many collections ONLY have wholebook submissions so chapter processed source type is irrelevant.
Current behaviour
You cannot create a collection unless you supply a source type for both wholebook and chapter processed submissions.

- Create collection
- Try to save without a chapter processed source type
Priority
Y, I believe this is a problem migrating content
