When the target pad disappears (because it was explicitly unlinked or the element was removed/unreffed) make sure we receive a notify with the unlink function on the proxy pad and clear the target. We use a simple flag to not do this and cause deadlocks when the target was changed explicitly using the ghostpad functions. Update the unit test because we now unref the target sooner (and correctly).
