Fix remaining duplication of batch jobs

I tested this and it didn't work. Here's a video:

Let me know if I'm testing incorrectly.

Moving to the Recipe Installer Kit project, which is what contains the business logic of the installer.

So one major technical reason I'm not sure about this change is because we cannot safely anticipate what will be included in RecipeRunner::toBatchOperations(). There may well be things in there that don't cleanly compare, or that aren't serializable, or...etc. That unpredictability makes this somewhat dangerous, and I'm not sure the risk-to-reward ratio is favorable enough to proceed.

Thoughts?

We're doing a strict check, so the worst that could happen is a few duplicate batch jobs slip through.

I discovered that most of the duplications I am seeing are coming from strict comparison when batch tasks are containing instances of Recipe object representing the same Recipe.
