Fix 3 things in test_urls:
1) We were expecting the absolute url but not asking for it - it's a bug in 3.0.x that we
   were returning the absolute url in that case.
2) Use assertRegexp instead of assertTrue(preg_match())
3) The hostname is "localhost" not "."
Update all tests.  No functional changes, but now they all pass - woot!
ORM::select_list() is gone, use an alternate.
