Add a test for early ticking

Ensure that we don't inadvertently start the connection if we call
SSL_handle_events(), or SSL_get_event_timeout() early.

This adds a test for openssl#25054, which was originally fixed by openssl#25069 to
ensure we haven't broken anything by the changes in the previous commit.
