We should only populate the 5 spec'd context.campaign fields when we parse the querystring. This PR adopts our utm parser's new strict mode to ensure that.
Our existing implementation will return an unbounded object with any key prefixed
utm_, causing, for example, unbounded column addition in redshift. This fix is especially important because customers are not in control of their own UTM params —any referrer can populate them erroneously and we see that happen often.@ndhoule @reinpk
cc/ @ivolo @wcjohnson11... you both were interested in seeing this fix through on slack :)
