Updating the SAFE min V2 template to the latest Saturn preview breaks Fable Remoting

[teknikal-wizard]

I tried to update a SAFE project to the latest Saturn 0.15.0-preview01 release, because it contains some important app builder updates.

This version of Saturn requires Giraffe 5.0.0-alpha-002.

When running the app after updating, the website will deploy but the UI is not connected, and I get this stack trace in the terminal:

fail: Giraffe.Middleware.GiraffeErrorHandlerMiddleware[0]
An unhandled exception has occurred while executing the request.

I have created a repro here: https://github.com/Ryan-Palmer-CIT/Safe-Saturn-Update-Bug-Repro

Looks like a compatibility issue. I think I need to better restrict the upper bound on the version of the Giraffe dependency
