Same as https://magnolia-cms.atlassian.net/browse/MX-70

On Norsu - when you do not supply a referenceDepth property on a delivery endpoint, then no references are resolved at all.

Expected behaviour is that the default value for referenceDepth is 1 (as documented) and that if you do not supply the property that reference resolving acts on the top level. (As it behaves in JCR)

Same problem happens with assetReferenceResolver and norsuReferenceResolver

Example configuration:

$type: pagesDeliveryEndpoint_v2
# referenceDepth: 2 

references:
  - name: imageReference
    propertyName: image
    referenceResolver:
      $type: assetReferenceResolver

  - name: activityReference
    propertyName: targetActivity
    referenceResolver:
      $type: norsuReferenceResolver
      targetWorkspace: activities
      expand: true
