webrtcbin: Add handling of unspecified peer-connection-state situation

For us it can happen that the DTLS transports are still in the process
of connecting while the ICE transport is already completed. This
situation is not specified in the spec but conceptually that means it is
still in the process of connecting.

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/758
