Deleting currently scoped project breaks session

[David Lapsley]

Horizon gets very unhappy if you delete the currently scoped project.

Here's how to reproduce:

1. Create a new project
2. Add current user to this project as an admin user
3. Change to the new project context
4. Delete the project from Admin/Identity/Projects

Horizon will return to the Projects view with an error message, but many views are broken due to the invalidation of the current token. Behavior will range from ISE to error messages.

Why would you delete the current project while scoped to the project?

[Nicolas Simonds (nicolas.simonds)]

Because users.

[Liz Blanchard (lblanchard)]

Would there be a case for a larger environment where a few users might be scoped to a certain project and an admin comes in separately and deletes it?

David, having hit this issue in Icehouse: Because Horizon hides the fact that you're currently still in the project/tenant when you switch back over to the admin tab.

I went into a project to delete a router, switched back to the admin tab, deleted the project and watched Horizon throw lots of errors at me because I was technically still in the project I just deleted.
