Duplicate snippets with Luasnip preset

[dpetka2001]

Make sure you have done the following

• Updated to the latest version of blink.cmp
• Searched for existing issues and documentation (try <C-k> on https://cmp.saghen.dev)

Bug Description

After commit c4eafc1, when you have Luasnip enabled in your personal configuration and you also set snippets.preset = "luasnip", you get duplicate snippets. Reverting to the previous commit does correctly show snippets only one time.

After c4eafc1 screenshot

Before c4eafc1 screenshot

Somehow the prefetch on insert gets duplicate items for Luasnip snippets.

Relevant configuration

snippets = {
  preset = "luasnip",
},

neovim version

NVIM v0.11.0-dev-1633+g851137f679

blink.cmp version

main

I have a similar case, but I noticed that the duplication occurs only when using the new syntax preset = "luasnip":

return {
    "saghen/blink.cmp",
    lazy = false, 
    dependencies = {
        "L3MON4D3/LuaSnip",
        version = "v2.*",
        dependencies = { "rafamadriz/friendly-snippets" },
        config = function()
            --- I had to add this option compared to the old syntax
            require("luasnip.loaders.from_vscode").lazy_load()
        end,
    },
    version = "v0.11.0",
    opts = {
        snippets = {
            preset = "luasnip",
        },

       .....

With the previous syntax this does not happen.

return {
    "saghen/blink.cmp",
    lazy = false, 
    dependencies = {
        "L3MON4D3/LuaSnip",
        version = "v2.*", 
        dependencies = { "rafamadriz/friendly-snippets" },
    },
    version = "v0.11.0",
    opts = {
        snippets = {
            expand = function(snippet)
                require("luasnip").lsp_expand(snippet)
            end,
            active = function(filter)
                if filter and filter.direction then
                    return require("luasnip").jumpable(filter.direction)
                end
                return require("luasnip").in_snippet()
            end,
            jump = function(direction)
                require("luasnip").jump(direction)
            end,
        },
        ...

Thanks @ruslanSorokin

I have not yet identified under what conditions but there seems to be edge cases where duplicates are still produced.

It happened to me twice today that at some point, duplicates would start showing up until I restart Nvim.
