fix: Outdated completion item with mini.snippets

[abeldekat]

Hello @Saghen,

I recently fixed this issue in nvim-cmp.

The problem also occurs in blink, and the fix is very similar.

Are there any drawbacks to the following approach?

.../completion/init.lua:

  -- trigger -> sources: request completion items from the sources on show
  trigger.show_emitter:on(function(event)
    vim.schedule(function()
      -- schedule to avoid outdated completion items
      sources.request_completions(event.context)
    end)
  end)

This would add latency to all of the sources. We want to get the request out to the LSP ASAP. I'll read up on that issue you linked soon
