Horizon crashes when deleting logged user primary project

[Guilherme Birk]

When the primary project of the logged user is deleted Horizon crashes with unauthorized errors.

1 - Create a project
2 - Create a user with admin role on the project recently created.
3 - Log in using the created user.
4 - In the projects panel, select the recently created project and delete it.
5 - Horizon crashes with Unauthorized errors when trying to retrieve the users/projects/image/... list.

I can see "Unauthorized errors", but Horizon does not crash.

It should logout in this kind of error.

Or warn "you are deleting yourself" first?

This is behavior is introduced by code fix from:
https://bugs.launchpad.net/horizon/+bug/1060426

It changed Horizon to prompt a message instead of logging out on unauthorized exception.
However, lots of functions did not handle the unauthorized exception in Horizon, and return exception to user directly.

I'd like to promote user error message and logout.
