1. Add a Link "View" in Recipe List page
2. upon clicking on "View" link, display the recipe details page.

when we try to delete a recipe after editing any of the entities referenced by it (Notes, Ingredients...etc), then the recipe can't be deleted a SQL Exception is thrown regarding referential integrity, saying.

org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: Referential integrity constraint violation: "FKAELN1FTJ8676MM6E78IU7IBWQ: PUBLIC.NOTE FOREIGN KEY(RECIPE_ID) REFERENCES PUBLIC.RECIPE(ID) (2)"; SQL statement:
delete from recipe where id=? [23503-200]

Steps to reproduce:

1. Start application.
2. Navigate to http://localhost:8080/recipe/1/update to update the recipe.
3. Change nothing and click the "Submit" button.
4. Navigate to http://localhost:8080/recipe/1/delete to delete the updated recipe.
5. Get the following error:

could not execute statement; SQL [n/a]; constraint ["FKDBFSIV21OCSBT63SD6FG0T3C8: PUBLIC.NOTES FOREIGN KEY(RECIPE_ID) REFERENCES PUBLIC.RECIPE(ID) (1)"; SQL statement: delete from recipe where id=? [23503-197]]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

Expected behavior:
You can delete the recipe after an update.

unable to find Recipe with id of 6 even though no recipe with that ID is created or set. After tracing this bug, It seems to happen on the RecipeRepository#save method call in RecipeServiceImpl#saveRecipeCommand
