Refactor test_vote_favorite

- Change variable names from nam1, nam2, nam3 to namg1, namg2, namg3, to clarify and remind us that they are Namings, not Names.
- After each `change_name`, reload each Naming which is being tested. Otherwise we’re simply assuming that `change_name` did not modify the Naming.
- Replace `assert_equal(false…` with `refute`; for brevity, readability.
- Replace `assert_true` with `assert`.  Ditto.
- Replace `assert_false` with `refute`. Ditto
