b:defx['paths'] dont update

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Environment Information

• defx version(SHA1): 3d36fea

• OS: Linux

Provide a minimal init.vim/vimrc with less than 50 lines (Required!)

" Your minimal init.vim/vimrc
set rtp+=~/test_nvim/defx.nvim/

The reproduce ways from neovim/Vim starting (Required!)

1. nvim -u init.vim
2. :Defx ~ and check b:defx.paths, for me, it is ['/home/zgp/']
3. :Defx ~ ~ and check b:defx.paths again, for me, it is ['/home/zgp/'], but ['/home/zgp/', '/home/zgp/'] be expected.
4. You will find that the paths are not updated to two item, If I don’t misunderstand the purpose of the paths.

Try to fix it

I found that the window recovery here ignores the changes of the paths: https://github.com/Shougo/defx.nvim/blob/3d36feaf41eb1c6a8411dae34964057783179ad1/rplugin/python3/defx/view.py#L320-L327

Unfortunately, it is feature. But you can understand easily than vimfiler which written in Vim script.

Sorry for that, maybe I didn’t express it clearly. I mean source code comment, defx implementation is difficult for me to understand, there is little comment on important data structures, I can only understand it myself, maybe my development experience is not enough. @Shougo
