bug: Run viur cloud setup gcloud in an empty project folder generates confusing results

[phorward]

Hello!

I'm currently experimenting with Google Cloud Shell and tried to run a viur cloud setup gcloud command in my home folder, with a fake project.json and no deploy folder.

$ viur cloud setup gcloud
Enter PROJECT_ID: xxx-viur3
Check if user is authorized with gcloud....

You should now be able to run your project locally with
   viur run 
At the first run, it might happen that some functions are
causing error 500 because indexes are not immediately
served. Therefore, maybe wait a few minutes.
Have a nice day.

This result is confusing. Generally, the workflow should in this case be something like viur init to initialize a new, empty base-project. viur cloud setup gcloud should fail immediatelly when there is no deploy folder, with a hint that viur init should be executed first.

viur init is in a separate issue #129
