Improve 'Set Recipe' throughput/simplicity

[Dreepa]

I was also confused by this.

I made all 5 logistic chests in one assembler, switching recipes, and I was like: "Why the heck does it not work?"

Until I realized, that I need to remove the trash from the assembler, before it starts another recipe, but it didn't occur to me that this would be necessary, because they all have the same ingredients.

What I intuitively expected was that the assembler already has the required items for the other recipe, since they are same.
Made no sense to me that I have to unload these ingredients, just to load them again from and into the same machine.
