* Restoring tracking of custom impressions without GA
In #15967 I (@jeremyf) introduced the "don't do tracking if Google
Analytics ID is blank". However, we still likely want to
trackCustomImpressions().
Further, I did some sleuthing and adding a couple of comments on whether
we should record page views for articles in draft status or any views by
the author.
* Ensuring we don't track views of author or unpublished
Prior to this commit, I was surprised to learn that we:
1) Tracked an author's view of their article.
2) Tracked views of an unpublished article.
This came up from a Forem creator asking if they could reset the view
counter. Or trigger the reset on publication.
I think a general business logic policy of don't track views for the
author and don't track views for unpublished articles is a reasonable
default.
Were we to pursue the clear views on publication, we'd need to consider
something that went from unpublished -> published -> unpublished ->
published. Without a more explicit state machine, triggering a
busineiss logic behavior seems a bit unexpected.
In other words, I wrote an article. There are 20 views when I realize
that I need to unpublished it. I make the changes in the unpublished
state, and re-publish. I'd assume that those 20 views would still be
"recorded" and counted towards my article's view counts.
* Revert "Ensuring we don't track views of author or unpublished"
This reverts commit 321ecbed0ac4552e175d39bf17655a2fc93b265c.
