World presets incorrect with tag

When using a datapack which replaces the `world_presets/normal.json` tag by using `"replace": true`, it will still use "default" world preset as first one. This way, I can't set another world preset as default. 

It would also be cool if the order from the tag would be the order when clicking the buttons.

For example:

{
   "replace": true,
   "values": [
      "minecraft:debug",
      "minecraft:normal"
   ]
}

This should result in default: debug, after pressing the button: normal.
