Validate that a job has a run playbook on freeze

We now know, before attempting to run a job, whether the inheritance
hierarchy has produced a main playbook for the job.  If there is none,
error early.

Also, in the executor, assume that any specified playbooks are
required to exist, and use the more specific version of the error
message if they don't.
