Test suite runs and passes!

Test suite runs and passes!

- Fixed some uses of UserRelation, which is now called UserRelationship.

- Fixed link generation on the users list.

- Removed some of the shabti cruft from the main test setup script.  The
  test suite now creates the entire database once at the very beginning,
  then drops everything at the very end.

- Stubber-ed out various stub controller tests that assumed an 'index'
  action which no longer exists.

- Changed the shabti test that assumes / contains a mention of Elixir.

- Removed the shabti tests which defined some bogus tables and then
  tried to use them, for reasons I cannot fathom.
