What is the issue you are experiencing?

If a user is deleted, their recipes still belong to them (or they might be deleted, or deleting the user might fail, depending on the database, I'm not sure). We should re-assign these recipes to another existing user, otherwise they'll be left with an invalid user id.

Steps to Reproduce

1. Create a new user
2. Log-in as the new user and create a recipe
3. Log-in as another user (admin) and delete the new user
4. Observe that the recipe's user_id is still the old user's id, which no longer exists
