[PATCH 2/2] completion: simplify _git_notes

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This also adds completion for 'git notes remove' with two options:
--ignore-missing and --stdin.

For some strange reason, 'git notes undefined --<tab>' completes --ref
without even running --git-completion-helper. But since this is an error
case (and we're not doing anything destructive, it's probably ok for now)
