* This method encapsulates a very simple test for the purpose of clarity.

* When a registered task is fetched, its object is unserialized.
* At that point, if the class corresponding to the object is not available anymore
* (e.g. because the extension providing it has been uninstalled),
* the unserialization will produce an incomplete object.
* This test checks whether the unserialized object is of the right (parent) class or not.
