Conflict with tanvirtin/vgit.nvim: `The coroutine failed with this message ... Invalid buffer id: 1`

Bug description

I'm not sure which plugin is the guilty here, so I'll open the same issue for both: https://github.com/tanvirtin/vgit.nvim/issues/214

VGit was working well when I was using neovim 0.6.1 version but when I updated to 0.7.0 I start getting this issue only when I use Shatur/neovim-session-manager with VGit. for simplicity and make sure that I am right, I've used ~/.config/nvim/simple-init.vim:

How to start Neovim with simple configuration file:

nvim -u ~/.config/nvim/simple-init.vim

The simple configuration:

let g:plug_home = '~/.config/nvim/plugins'

call plug#begin(plug_home)
Plug 'nvim-lua/plenary.nvim'
Plug 'tanvirtin/vgit.nvim'
Plug 'Shatur/neovim-session-manager'
call plug#end()

lua << EOF
require('vgit').setup()
EOF

The error message:

Error executing vim.schedule lua callback: ...ig/nvim/plugins/plenary.nvim/lua/plenary/async/async.lua:14: The coroutine failed
 with this message: .../nvim/plugins/vgit.nvim/lua/vgit/features/LiveGutter.lua:30: Invalid buffer id: 1

I think that the issue is on VGit side. When I loading session, I remove all old buffers and VGit should be able to restore its state after buffers cleanup. Here is the code which is responsible for it:

https://github.com/Shatur/neovim-session-manager/blob/f0b0501ed4c311adc24fa00f27f17694faeb36a9/lua/session_manager/utils.lua#L51-L58

I had a similar issue with nvim-scroll: https://github.com/dstein64/nvim-scrollview/issues/70

@MuhammadSawalhy:

You can use my plugin as a temporary fix: https://github.com/nyngwang/NeoNoName.lua. Add this to your config file:

vim.cmd([[
  augroup VGitFix
    au!
    au VimEnter * NeoNoNameClean
  augroup END
]])

I design NeoNoNameClean as a function to remove all redundant [No Name]-buffers. After running this command you will have only one (valid, listed) [No Name]. I don't pretty sure why this can fix the problem, but it just works :)

@MuhammadSawalhy: FYI: the method in my previous comment doesn't work now :(

[MuhammadSawalhy]

This issue doesn't happen anymore. I think somewhere the bug was fixed in NeoVim or either of the plugins.
