Bugfix: Make sure we wait until 'count' servers have launched in the Launch actor.

The rightscale.server_array.Launch actor optionally takes a 'count' of
servers to launch -- but when it comes time to monitor how many servers
are running, it was only looking at the ServerArray 'min_count' rather
than actually paying attention to the count supplied by the user.

Bugfix: Destroying a non-existant server array should return False.

There were two bugs here...

1. Logging string problem (unmatched %s).
2. The Destroy actor needs to pay attention to whether the Terminate
actor succeeded. If it fails, then we immediately fail the Destroy actor
too.
Issue: #73 - GenericHTTP actor.

* Unify mock_tornado() and tornado_value() helper functions during testing.
