manage.py setup --authz is broken

[mhrivnak]

We added the "--authz" option so that developers can change ACLs, then blow away the old ones and load the new ones without having to reset the entire DB.

I am seeing this behavior:

$ ./manage.py resetdb
$ ./manage.py setup precor

things work as expected. Then:

$ ./manage.py setup precor --authz

permissions change. I specifically see that for the Org Administrator, they can no longer read the Organization table.
