tests: add test for empty CA certs file
smf reported that an environment with no loaded CA certs resulted
in a weird error. I'd like to detect this a bit better so we can
display an actionable error message.
The actual error being globbed over in this patch is "unknown error"
with a ssl.c line number. That isn't useful at all.
