Use actual remaining items to calculate remainders for basin recipes

[PssbleTrngle]

This is a proposed fix for #6963.

This PR solves the there mentioned problem by using the same method to calculate remainder items as it is used for shapeless crafting recipes.

Here are two example recipes to test the bug and it's solution with:

Recipe 1

{
"type": "create:mixing",
"ingredients": [
  {
    "item": "water_bucket"
  },
  {
    "tag": "forge:ingots/zinc"
  }
],
"results": [
  {
    "count": 2,
    "item": "diamond"
  }
]
}

Recipe 2

{
"type": "create:mixing",
"ingredients": [
  {
    "item": "water_bucket"
  },
  {
    "item": "lava_bucket"
  }
],
"results": [
  {
    "count": 1,
    "item": "obsidian"
  }
]
}
