Fix potential use-after-free issue

NuPlayerListener passed this out of its constructor to
IStreamSource->setListener, and it would get wrapped in a smart pointer,
then free'd when that method returned.

Move the setListener call after instantiation of NuPlayerListener to
avoid passing this out of the NuPlayerListener constructor.
