Currently, in that case it was failing because watcher tried to create a
name based on a goal automatically and the goal is not defined.
This patch is moving the check for goal specification in the audit
creation call earlier, and if there is not goal defined, it returns an
invalid call error.
This patch is also modifying the existing error for this case to check
the expected behavior.
