Extracting an App loses all of the enumerations!!!

(Bug, Investigate , Priority: Critical, Test Status: No automated tests yet , Reported By Justin du Coeur, )
Apps
Summary: After extracting an App, the original Space no longer shows enumeration values in the drop-downs when creating new Things!
This one is a P0, because it actually breaks the original Space -- that's extremely not-okay.
Look at the Copy of Issues Space on my dev machine: after extracting an App, creating a new Issue is very broken.
