Sorry, to be clear, I meant that you should create an /_ah/channel directory at the top of your war and copy dev-channel-js.js so it is a file named 'jsapi' in that /_ah/channel directory. This is the path that will work automatically in the 1.3.6 DevAppServer and in prod when this feature launches publicly.
If you name the script something else (as you've done), that will work fine for now but you'll need to remember to adjust the path later.
