Previously we ensured that `AvaloniaObject.SetValue` was run on the main thread. This makes sure that `GetValue`, `IsSet` and `ClearValue` are also run on the main thread. Unit testing this turned out to be more complicated than expected, because `Dispatcher` keeps a hold of a reference to the first `IPlatformThreadingInterface` it sees, so made `UnitTestApplication` able to notify `Dispatcher` that it should update its services.pull/909/head
