function ExtensionSerializationTest::testServiceAppRouteUsage

Tests that the Extension class unserialize method uses the preferred root.

When the Extension unserialize method is called on serialized Extension object data, test that the Extension object's root property is set to the container's app.root and not the DRUPAL_ROOT constant if the service container app.root is available.
