Temp files not being cleaned up

[RonGee]

Currently on Debian dehydrated 0.7.0

I can't figure out where it's happening, and it doesn't happen every time (looks like maybe just for failures) but I'm noticing there are temp files not being cleaned up. These files contain on one line, all the names in the certificate being requested, ie: "example.com *.example.com" or "example.net www.example.net"
