Test case

In the attached test case I create a playbin2, set a video sink, play
a video for some time, then stop it, set the pipeline to NULL and set
a new video sink to the pipeline.

At this point I'm expecting the old sink to be destroyed and replaced
by the new one, but if I query the pipeline I still get the original
video sink, which by the way increases its reference counter each time
I repeat the process.
