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.

To run the tests, do:

cd tests/
python run-tests.py
