RecreateWebRtcStream was checking the "sending_" flag, but wasn't checking rtp_parameters_.encodings[0].active. As a result, if an application calls "RtpSender.setParameters(inactive_params)" then later the stream is recreated due to some change in SDP parameters, the stream would incorrectly start sending.
