Certificate failure results in multiple emails

[humphd]

I ran into a weird bug on staging, and my certificate request failed. I ended up getting 2 failure notification emails (both identical):

I guess the cleanup code and failure code are both doing it for some reason?

I tried it again, and when it worked, I only receive a single email.
