Code review comment for ~steverydz/maas:fix-machine-listing-js-error

I couldn't find out exactly what's happening, but I think that there is a cache for each object that gets updated when you go and view the object individually, since you generally need to get more information. Then when switching back to the list, the cache isn't updated, since it's expected that you don't loose information when viewing the object individually.

I've created a new MP for the proper fix:
