Working directory is wrong when launching Neovim by specifying a directory.

[guilhermerodz]

OS
Ubuntu 20.04.3 LTS (Focal Fossa)

Neovim version
0.7.0-dev

Nvim-tree version
ea92e7b

Describe the bug
Since 8a6c7ba, the working directory is no longer synced EVEN if I specify a directory when launching Neovim.

(dropped a few guesses of mine at the end of this issue)

To Reproduce

On Terminal:

$ cd ~/a # navigate into folder A
$ nvim ~/b # attempt to launch nvim on folder B

Inside Neovim:

:pwd
/home/guilhermerodz/a << Should be "b" not "a".

NOTE: This behaviour wasn't happening before this commit: 8a6c7ba.

Expected behavior

• When launching Neovim, nvim-tree should automatically set the current working directory if specified in the command line.

• MAIN GUESS: I know there are very recent refactors. I think this issue is related to nvim-tree/explorer/init.lua. The Explorer.new(cwd) method is called. A new Explorer instance is created, then the cwd variable is set. But this logic causes Explorer's cwd to be unsynced with Neovim's current working directory, which remains unchanged.
• A NOTE: I took some time to compare our updated version to an older version. In the current version, at nvim-tree/actions/change-dir, the M.fn method stopped being called at startup.
