bug: lightbulb doesnt work properly

[arztareef]

Describe the bug

Screen.Recording.2024-12-12.at.10.42.15.PM.mov

the bug: sometimes the bulb displays the bulb on a line even when a code action isnt available

Steps to reproduce

step 1: use the plugin config provided below:

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    'nvimdev/lspsaga.nvim',
    config = function()
      require('lspsaga').setup({
        lightbulb = {
          enable = true,
          virtual_text = false, -- happens w/ virtual_text as well though.
        },
        ui = {
          code_action = '',
        }
      })
    end,
  },
})

step 2: open a lua file w/ lua_ls LSP
step 3: type pr in insert mode
step 4: delete the pr line using dd motion

if all done correctly, the lightbulb should stay in the line deleted after 'pr' like the video provided above

Expected behavior

The code_action sign should be removed when there isnt a code action available for the line
