Get server fault if snapshot fails

When we get a 404 from Glance because a server snapshot
is not found while we're waiting for it to be ACTIVE, it
means Nova deleted the failed snapshot from Glance because
something failed in nova-compute during the snapshot
operation.

Rather than just dump a 404 in the test console output on this
type of failure, this change gets the server which should have
a fault recorded and uses that to raise a more useful error
message for the test output.
