Don't show 'waiting for media' on connected participants

We would show 'waiting for media' on participants that were connected but had no published tracks, because we were filtering them out of the remote participants list on connections. I believe this was done in an attempt to limit our view to only the participants that have a matching MatrixRTC membership. But that's fully redundant to the "Matrix-LiveKit members" module, which actually has the right information to do this (the MatrixRTC memberships).
