Saving notes for a project using "Pn -" seems not to work

[newlog]

The asciinema explains the issue:

https://asciinema.org/a/8l5nw0jpc7512ri5akeip2joc

Basically, as I understand it, the note is attempted to be saved in the <project_name>.d directory, but that directory does not exist.

After @Maijin comment:

The commands I executed, follow:

1. open r2: r2 /bin/ls
2. Save/Create project: Ps dummy_project
3. Create note with default editor (vim): Pn -
4. Type text in vim
5. Save contents in vim by executing: Esc :wq
6. Save operation through vim failed

My guess: directory dummy_project.d does not exist, so vim fails to save the file when :wq
