Ch 1338 - Don't pause agents automatically on changes

However - with this said, right now it would only be called to update the verification cache if the agent is running and gets paused.  It's possible for the agent to go from not running and invalid to valid, or paused and invalid to valid.  Essentially this cache is what is used to determine whether or not the "start/resume" link is active and that change can happen while the campaign isn't running.
