- What is the current behavior?

List fields do not default to an empty array

- If the current behavior is a bug, please provide the steps to reproduce.

1. Create a collection with a list field that has no default value
2. Attempts to save the collection without populating the list field with an empty object will fail with a crash.
3. Adding a default: [] entry to the list field fixes the issue

- What is the expected behavior?

List fields should always default to an empty array without user intervention.

- Please mention your CMS, node.js, and operating system version.

CMS version: v0.5.0
Node.js version: v8.6.9
OS version: Varies, Ubuntu LTS or OS X
