Engine Crash when Running a Screenshot Functional Test

Running a Screenshot Functional test, is causing an engine crash.

By attaching a debugger to it, AScreenshotFunctionalTestBase::PrepareForScreenshot() is reached and GEngine->GameViewport is null, so it looked like the world for the test might be created as "RunAsDedicated" (PlayLevel.cpp -> CreateInnerProcessPIEGameInstance() ) therefore doesn't get a ViewportClient created & assigned.

1. Drag the actor in an empty scene
2. Saving the scene
3. Running the test from the Sessions frontend
4. Observe crash
