function BreadcrumbPreprocessTest::testEntityWithBundleKeyButNoBundleEntity

Tests an entity type whose bundle key does not resolve to a bundle entity.

The entity_test type declares a bundle key but no bundle entity type, so its bundle field is a plain string and reading ::entity off it yields NULL. Calling ::label() on that is a fatal error, which took down every edit form of every such entity type, menu links among them.
