[Do Not Merge] Org & Loc tests UI: Dependent Entities use now APIs

The dependent entities now use APIs to create them.

Now `ui/test_location` and `ui/test_org` now uses `FauxFactory`
module for generate_string, generate_ipaddr, generate_email.
Note that there is no guarantee any of these factories will work, given that they have no associated tests. It's OK to do this, but just be aware.
