find_file doesn't work when group_empty option is enabled

[liljaylj]

Description

find_file api action does not focus grouped directory node if group_empty config option is enabled.

i use this functionality when i try to edit directory either with :e a/b/c or nvim a/b/c, nvim-tree window with mentioned dir focused.

NOTE: minimal config is adapted from lazy.nvim

  local bufnr = data and data.buf or vim.api.nvim_get_current_buf()
  if not bufnr or not vim.api.nvim_buf_is_valid(bufnr) or api.tree.is_tree_buf(bufnr) then

  -- buffer is a directory

_G.setup = function()
  require('nvim-tree').setup {
    disable_netrw = true,
    hijack_directories = {
      enable = false,
    },
    hijack_unnamed_buffer_when_opening = false,

    callback = vim.schedule_wrap(open_dir_buf),
  })
end

Steps to reproduce

1. create directory structure like this:

.
├── a
│   └── b
│       └── c
│           └── d
│               └── e
└── q
    └── w
        └── e
            └── r
                └── t
                    └── y

12 directories, 0 files

2. nvim -nu /tmp/nvt-min.lua a/b/c (in directory from previous step)
3. after packer init nvim-tree window should be opened, but directory is not focused

Expected behavior

NvimTree open with directory is focued

Actual behavior

NvimTree open but directory is not focued
