Move v3 project negative tests to work w/ pre-prov

I don't see any limitations by using pre-provisioned
credentials for these tests:

* test_list_projects_by_unauthorized_user
* test_project_create_duplicate
* test_create_project_by_unauthorized_user
* test_create_project_with_empty_name
* test_create_projects_name_length_over_64
* test_project_delete_by_unauthorized_user
* test_delete_non_existent_project

Note that these tests aren't interop tests [0] so can
be safely moved.
