webrtc: request-aux-sender, only sink floating refs

Browse source 
Don't add an extra ref if non-floating as that ref will never be
unreffed.

gst_bin_add() is transfer floating (alias to transfer none).

Fixes a leak when a non-floating ref was provided as a return value in
the request-aux-sender signal.
