Introduced test to validate Version is available on TopicLoaded event

JeremyCaney · JeremyCaney · commit 9f63d37bb1c7 · 2021-03-18T13:26:44.000-07:00
The `TopicLoadEventArgs` event has an optional `Version` property that should be populated when loading a specific version. This test currently fails due to a bug in the `StubTopicRepository` test double, which will be fixed in a subsequent commit.
