Fixes for rapid successive setMedia requests

Add some workarounds (possibly a little kludgy) so that if setMedia is
called in rapid succession while the player is currently playing,
ConnectionManager can properly shut things down and handle closed
connections, and short-circuit any active connection attempts (what a
pain!) and edge case, but easy to run into.
