Kristina's Ada Cooks

1. I skipped Silver.
2. I'd like feedback/tips especially on the tests. I feel a little lost with Rspec and Rails.
3. Thanks for reviewing! :)
This test is failing for me:
```
  1) Recipe self.search_by_ingredients returns a recipe associated with an ingredient matching search term
     Failure/Error: expect(ingredient_names.any?).to be true
       
       expected true
            got false
```
