Experimental fix for solving replacement of mic audio when enabling screenshare audio on windows electron

On Windows Electron, startWithElectronDesktopCapturer uses getUserMedia({ chromeMediaSource: 'desktop' }) for both video and audio. This getUserMedia desktop audio call can interfere with / replace the existing mic getUserMedia stream, killing voice audio.

BREAKING CHANGE: possibly streaming
