Title: Fix a problem with the implementation of dexterity support at plone.app....

...linkintegrity,

when this behavior is used with plone.app.referenceablebehavior the delete_confirmation form
was failing because the object than is being deleted doesn't have an intid.
With this patch the get_relations method simply returns an empty list in this case.
