Conform LifeformsControllersTest params to updated form

- Fixes bug in test:
```ruby
 FAIL Names::LifeformsControllerTest#test_edit_lifeform (159.03s)
        Expected: " lichenicolous "
          Actual: " "
        test/controllers/names/lifeforms_controller_test.rb:26:in `test_edit_lifeform'
```
- Lifeform form now uses params[:lifeform][:<form>] rather than params[:lifeform_<form>]
