Missing bundle id in pdxinfo gives weird image loading errors

Hi!

Using the 2.6.2 SDK and I've missed giving the pdxinfo a bundleId at all. When trying to load an image, I got

warning: access to ANY_IMAGE_YOU_TRY_TO_LOAD is not allowed on the device

in the Simulator.

I would suggest, to have a warning if the pdxinfo is invalid to prevent beginners like me to search for the issue of the image loading.
