zhihuang f816493c4f Add media related stats (audio level etc.) to unsignaled streams.
The media related stats wasn't working for unsignaled stream because there
is no mapping between the receiver_info and unsignaled tracks.

This CL fixes the issue by adding some special logic to the TrackMediaInfoMap
which would create the mapping.
