Fix too much recursion error during update_location_tree...

Fix too much recursion error during update_location_tree. Don't traverse descendents during the all-locations update. Actually disable update_location_tree during prepopulate.

Had to split off disabling the location tree update from auth.override, as they were at cross purposes elsewhere.
I need the name of the logger in a test. The name is not the name of the class. The name is applications.[directory].modules.s3log
