Fix flaky test WebRtcMediaRecorderTest.PeerConnection

A previous CL changed from logging to DCHECKing when setting minimum playout delay on a VoE channel: https://codereview.webrtc.org/2452163004/

I thought it safe at the time, since the input parameter range is capped, but apparently I didn't dig deep enough, as ultimately a failure may be returned for other reasons: https://chromium.googlesource.com/external/webrtc/+/master/webrtc/modules/audio_coding/neteq/delay_manager.cc#381

Thus, reverting to old behavior.
