nvim-tree does not open after an in-place open with eject=false

[usachev63]

Description

In #2341 I introduced a bug which happens only with eject = false option. Turns out, when making an in-place open with eject = false, the window, in which nvim-tree buffer is overridden with a new file, is still considered a nvim-tree window. Thus, when we try to open nvim-tree, we have view.is_visible == true an the tree is not opened.

I figured out the fix and will provide PR very soon. The issue is to put a clean room example in history.

Neovim version

NVIM v0.10.0-dev
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

Operating system and version

Linux 5.16.15-051615-generic

nvim-tree version

end

Steps to reproduce

1. nvim -nu /tmp/nvt-min.lua
2. :NvimTreeOpen
3. :e nvt-min.lua
4. :NvimTreeOpen

Expected behavior

The nvim-tree window opens.

Actual behavior

Nothing happens: nvim-tree window does not open.
