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.

Fixed the organization and location tests as per comments.

Few Fixes after the rebase
Merge pull request #1394 from kbidarkar/update-location-ui-tests
