[PATCH 2/2] winegstreamer: Respond to the URI query.

[Brendan McGrath]

From: Brendan McGrath

The default behaviour for gstreamer is to use the URI to create the
stream-id. Without this, gstreamer creates a random stream-id per pad
which can cause inconsistent ordering on the decodebin src pads.

This in turn can cause issues, for example, with audio stream selection.
