Removing Default Warehouse prevents web app from starting

We get the warehouses from integration, so I thought I'd remove the Default Warehouse since we do not use it. Didn't think about it, I just did it. Little did I know that the web app would not be able to start anymore without it.

To me, this is definitely a bug. Don't allow the user to do this if it has such catastrofic effects.
