Add ssl_ctx_test to test suite.

Also fix the test as min version > max version is allowed because
the API calls to set min and max versions are separate and there
can be legitimately a temporary situation when the condition is
true even with correctly working application.

The failure in this condition will be detected only during
a handshake attempt.
