Delete console negative tests

These autogenerated tests are wrong in at least 2 ways, one is
assumptions about when servers are available, and the other a schema
which makes assumptions about the resource end points that are
provably wrong when you look at the Nova code (which is unchanged for
2 years).

It's not clear there is any value generated from these tests, suggest
to delete them.
