Subject: webrtcbin: connect rtp funnel after updating ptmaps
X-Git-Tag: 1.19.3~507^2~2389

webrtcbin: connect rtp funnel after updating ptmaps

We need the streams' pt maps updated before requesting pads
on rtpbin, because this is what will trigger the requesting
of FEC encoders, and our handler for this request looks for
the payload types in the relevant stream's pt map.

Fixes #1187
