Jason app shows tab bar url warning even with matching url

The Jason app currently in the App Store (4.0) displays a warning dialog that at least 1 item in tabbar must have same url as the current view, even when one of the items *does* have the same url.
The url in use for the loaded view and first item in tabbar is a local IP with non std port in case that is affecting the check, eg `192.168.1.117:8080/app.json`

Start by reproducing the warning in the Jason app with a tab bar URL matching the current view, including a local IP and non-standard port such as 192.168.1.117:8080/app.json. Trace the tab bar URL check and confirm that the warning no longer appears when a matching item is present.
