Extracting constants and tidying tests (#15946)
Prior to this commit, we had a couple of references to magic strings
regarding DisplayAdEvent objects.  This commit seeks to consolidate that
behavior.

In a handful of cases we had javascript variables, but as these JS files
are `erb` templates, we can inject the constant as well.  This reduces
repetition of knowledge.
