[MC-91342] Spider and poison spider loot is changed

Cave spider and spider have different drop than before.
In 1.8.8 they dropped 0-2 strings and 33% of dropping 1 spider eye.
With looting 3 they dropped 0-5 strings and about 80% chance of dropping 1 spider eye.
In 15w43c they drop 0-2 strings and 33% of dropping 1 spider eye like in 1.8.8, but with looting they can drop up to 4 spider eyes, where chances are unaffected with looting.

Now loot table is:

{
    "pools": [
        {
            "rolls": 1,
            "entries": [
                {
                    "type": "item",
                    "name": "minecraft:string",
                    "weight": 1,
                    "functions": [
                        {
                            "function": "set_count",
                            "count": {
                                "min": 0,
                                "max": 2
                            }
                        },
                        {
                            "function": "looting_enchant",
                            "count": {
                                "min": 0,
                                "max": 1
                            }
                        }
                    ]
                }
            ]
        },
        {
            "rolls": 1,
            "entries": [
                {
                    "type": "item",
                    "name": "minecraft:spider_eye",
                    "weight": 1,
                    "functions": [
                        {
                            "function": "set_count",
                            "count": {
                                "min": -1,
                                "max": 1
                            }
                        },
                        {
                            "function": "looting_enchant",
                            "count": {
                                "min": 0,
                                "max": 1
                            }
                        }
                    ]
                }
            ],
            "conditions": [
                {
                    "condition": "killed_by_player"
                }
            ]
        }
    ]
}

but it should be:

    "pools": [
        {
            "rolls": 1,
            "entries": [

                    "functions": [
                        {

                            "count": {
                                "min": 0,
                                "max": 2
                            }
                        },

                            }
                        }
                    ]
                }
            ]
        },
        {

                    "chance": 0.33,
                    "looting_multiplier": 0.15
                }
            ],
            "rolls": 1,
            "entries": [
                {

        }
    ]
