function MessageTest::testRelationships

Tests CRUD of individual resource relationship data.

Unlike the "related" routes, relationship routes only return information about the "relationship" itself, not the targeted resources. For JSON:API with Drupal, relationship routes are like looking at an entity reference field without loading the entities. It only reveals the type of the targeted resource and the target resource IDs. These type+ID combos are referred to as "resource identifiers."
