StoryboardLoadable protocol doesn't work with `AnyWorkflow.PassedArgs`

[Richard Gist]

Woah...there was a deep underlying issue with SwiftCurrent altogether here. Short version? When the input type was AnyWorkflow.PassedArgs it was not using the factory method. Meaning all the StoryboardLoadable protocol things simply don't work with AnyWorkflow.PassedArgs, you can discover this yourself if you simply don't use PassthroughFlowRepresentable.

I can try to fix that as part of this issue, but it feels like this'll get stuck on behalf of a bug that has nothing to do with this new feature for a while.
