  [GStreamer][WebRTC] Potential null dereference on webrtcbin
https://bugs.webkit.org/show_bug.cgi?id=258724

Reviewed by Xabier Rodriguez-Calvar.

In a situation where the webrtc plugin is not available we might end up destroying an end-point that
has no webrtcbin element, so we need to check this before disconnecting signal handlers.
