Wrong behavior in Processing Patterns when double requesting a resource made in a machine with a full buffer

[EspiMKII]

Describe the bug

Originated from a report of a friend having trouble with Modern Industrialization recipe, I've tried to reproduce the bug he encountered.

Example recipe: smelting recipes, via a Mekanism's Ultimate Smelting Factory (because i dont feel like waiting for that long... I've wrested with this bug for 3 days straight).

While an Autocrafter is attached directly to the Smelter, requesting 2 batches of the same item (and make sure both batches will make the smelter full, so the Autocrafter cannot push all the ingredients into the machine at once) results in 1 of the 2 jobs never finish. Upon closer inspection via the Autocrafting Monitor, it seems that the network never pushed enough materials into the Smelter, and thus not enough outputs were retrieved. The behavior of the 2 jobs in the Monitor will be shown in the reconstruction video below.

Note, this bug was not very consistent to reproduce, and I had a lot of trouble setting up my testing instance to do it semi-consistently. From my modlist without the next 3 mods, I tried adding Cable Tiers and Refined Types, then Modern Industrialization, then removed all 3 of them, then added MI again, then removed MI again, and only now is the reproduction somewhat consistent.

1. Set up a simple RS network with a controller, some storage, a Grid, and an Autocrafter hooked to a processing machine, obviously with valid patterns.
2. Request a resource twice, ensuring both requests should fill up the machine's buffer completely (so the Monitor will say "Machine doesn't accept resource").
3. Observe the jobs' behaviors in the Autocrafting Monitor.
4. Observe in the Grid if the system has obtained the correct amount of product.
