Philippe Normand 5cfa9dc0e0 webrtcbin: Prevent crash when attempting to set answer on invalid SDP 
If the pending remote description has an invalid BUNDLE group _parse_bundle()
triggers early return from _create_answer_task(), before ret has been
initialized, so it needs to be checked before attempting to call
gst_sdp_message_copy().
