function FieldBulkDeleteTestCase::testDeleteFieldInstance

Verify that deleting an instance leaves the field data items in the database and that the appropriate Field API functions can operate on the deleted data and instance.

This tests how EntityFieldQuery interacts with field_delete_instance() and could be moved to FieldCrudTestCase, but depends on this class's setUp().
