Tests: avoid $ssl_session_reused tests failure with OpenSSL 1.1.0. Closing a connection without close_notify worked by an accident, until it was considered a bug and fixed in OpenSSL 1.1.0: https://git.openssl.org/?p=openssl.git;h=e70656c Note though that as of TLS 1.1, failure to properly close a connection no longer requires that a session not be resumed.
