Subject: Take local copy of UMP::local_sources to iterate
Take a local copy of UserMediaProcessor::local_sources_ when iterating
over it in UserMediaProcessor::DetermineExistingAudioSessionId, as the
list can be effectively concurrently modified during destruction of
MediaStreamTracks triggered by GC during this loop. Without the copy
this leads to a container overflow.
