Check if app_id is in url path
app_id must be included with each request. In order to reduce load on the server we fail requests early on the client that we know will fail on the server. Currently the check in OneSignalRequest looks for app_id in the body as a param. However there is another valid way to send the app_id that is after "/apps" in the path".
