(Sorry, I confused this bug with bug 1497928. This one is not a good-first-bug, so let me adjust the flags)

So the issue here is that the certificate could be in up to three locations, so there was no clever way to know at the end that no certificate was found.

Sure.

If you look here:

https://searchfox.org/mozilla-central/source/browser/components/enterprisepolicies/Policies.jsm#141

You'll see that we look in multiple locations for the certificates.

Because the certificate can be in one place and not another, we don't want to show an error every time we don't find a certificate.

We want to keep track of our search for the certificate and if we never find it, show an error.

So I actually fixed this as part of the rewrite in bug 1506734.

I'll be more than happy to find another bug for you to look at.
