Tests: fixed test_tls_reconfigure.

Previously, order of applying TLS configuration and sending partial request to
the application was uncertain.  These changes make sure that client-application
connection was established before reconfiguration.  Additionally, added test
to check that non-TLS connection works correctly after reconfiguration.
