This change fixes a bug when the page does not have an analytics provider setup. In
this scenario TrackingTags.analytics() assumes Google analytics and then errors because
_gaq is undefined. This error keeps all subsequent JS from executing. This causes the
refreshing of CSRF tokens on turbolinks:load not to run and many forms to raise
InvalidAuthenticityToken.
Fixes #5464 and #5470
