NERDTreeCWD and autochdir do not cooperate

[segeljakt]

Not sure if this is a bug or not, NERDTreeCWD appears to change directory to the :pwd of the NERDTree's buffer and not to the current buffer's when using autochdir.

Environment

• OS: macOS High Sierra
• Editor: MacVim
• Version: 8.1
• NERDTree version: d6032c8

Process

1. mvim ~/
2. :set autochdir
3. :cd ~/test/
4. :NERDTreeCWD

Current Result

NERDTree's root is the ~/.

Expected Result

NERDTree's root should be the ~/test/.

It works when changing the second step (2.) to :set noautochdir.

I tracked this error down to this line in creator.vim. For some reason it changes the CWD when 'autochdir' is turned on, but... only when it's run as part of the :NERDTreeCWD command. Strangely, executing the command :topleft vertical 42 new manually has no effect on the CWD.
