Allows definitions with objects

[bradleymarques]

Background:

Definitions that were type: "object" caused the following error:

Example:

const jsonSchema = {
  type: 'object',
  definitions: {
    address: {
      title: 'Address',
      type: 'object',
      properties: {
        country: { title: 'Country', type: 'string' },
        addressLineOne: { title: 'Address line one', type: 'string' },
      },
    },
  },
}

Cause:

The root cause of the issue was that dataOptions was being lost for things deemed "sections".

Fix:

Assign dataOptions for both "sections" and "cards"
