Zap run_in_prod. [1/1]

We only create the Chef jig via the Rake task to inject chef
connection information, and we force the BarclampChef::Jig class to be
a singleton and refuse to create its instance if the server info is
not populated in the database.

Because of that, we no longer need to guard against doing chef jig
stuff in the unit test environment.
