Enable naming new notes with :NewNote arguments

:NewNote doesn't warn about existing notes with the same name because one
of my next commits will rename :NewNote to :Note and make it open existing
notes instead of creating a new buffer with the same name (to avoid
confusion / accidental overwriting of notes).
