Throw exceptions of SSLSocket.startHandshake() in connect()

instead of throwing a NoResponseException in case startHandshake()
throws an Exception. The NoResponseException was then thrown when
performing SASL auth, which usually directly followes securing the
connection via TLS (if enabled and provided by the server).
