Subject: [PATCH] feat(JitsiConference) Allow adding multiple tracks to the
 conference. This should be supported by the backend. This limitation was
 added here only because of track synchronization issues between JM and LJM.
 The support is added behind testing.allowMultipleTracks config.js setting
 Fixes https://github.com/jitsi/lib-jitsi-meet/issues/2205
