outline and winbar symbol error

[JuanZoran]

Describe the bug

• I just update this plugin, and I use lspsaga outline to get these messages: Do you know how I can fix that?

  Error executing vim.schedule lua callback: vim/_meta.lua:0: unknown option 'stc'
  stack traceback:
  [C]: in function 'nvim_get_option_value'
  vim/_meta.lua: in function '__index'
  ...e/pack/packer/start/lspsaga.nvim/lua/lspsaga/outline.lua:60: in function 'set_local'
  ...e/pack/packer/start/lspsaga.nvim/lua/lspsaga/outline.lua:153: in function 'create_outline_window'

  /usr/share/nvim/runtime/lua/vim/lsp.lua:1391: in function ''
  vim/_editor.lua: in function <vim/_editor.lua:0>

• I use lualine for winbar processer and I add these code in lualine config, I get these:

  
      lualine_c = {
          {
              -- require('lspsaga.symbolwinbar'):get_winbar(),
              -- on_click = handler,
          },
      },

Error in packer_compiled: ...k/packer/start/lspsaga.nvim/lua/lspsaga/symbolwinbar.lua:2: attempt to index field 'config' (a nil value)

thanks for your reply

### Steps to reproduce

- add `        lualine_c = {
            {
                -- require('lspsaga.symbolwinbar'):get_winbar(),
                -- on_click = handler,
            },
        },
` into lualine config
- use `lspsaga outline` in some lua file
