Due to the change in python versions greater then 2.7.8, messages
that SSL certificate handling module is producing are different
from the error messages produced in earlier versions of py27.
Fixed how the following test cases of TestHTTPSVerifyCert class
are handling erroneous SSL certification messages:
- test_v2_requests_valid_cert_no_key
- test_v2_requests_bad_cert
- test_v2_requests_bad_ca
