Fix incorrect javadoc references in JobContext

JobContext was created by copying StepContext (as noted in the
@author tag), but the javadoc for close() and getId() was not
updated to reflect the job execution context. This commit fixes
the references from "step execution" to "job execution" and from
StepScope to JobScope.
