I haven't noticed any crash yet.
But libwebrtc network process may well keep the last reference to LibWebRTCMediaEndpoint, thus deleting objects that are supposed to be deleted in the main thread.

We should fix the style checker if we really want to allow one initializer on the same line.

This shouldn't have its own line.
