refs #4996 there is a difference between link tracking enabled and installed. When replacing the initial link urls link tracking might not be installed yet but enabled (will be installed on load event). When a click is happening on a content block we still need to use linkTrackingInstalled since then the credirect/tracking request is actually happening and we need to know whether outlink/download will track it or whether we have to do it separately. Make sure to call enableLinkTracking before trackContentImpressions although there should be no huge difference as both will be delayed until ready/load event anyway
