[BUG] gitk update/reload doesn't refresh notes

Hi,

I would expect that when I start gitk with '--show-notes' option and press update or reload, then it updates not just the commits, but the notes shown in the log/diff window, too. However, as shown below, this is not the case.

  notes_vs_gitk$ git init
  Initialized empty Git repository in
  /home/szeder/tmp/git/notes_vs_gitk/.git/
  notes_vs_gitk (master)$ echo 1 >foo
  notes_vs_gitk (master)$ git add foo
  notes_vs_gitk (master)$ git commit -m First. foo

  notes_vs_gitk (master)$ git notes add -m "Note,
  that these notes will not appear in gitk without restarting it"

  # Press F5 in gitk for update.
  # Nope, notes are not shown.
  # Press ctrl-F5 in gitk for reload.
  # Notes are still not shown.

  # Notes are shown, finally.

  notes_vs_gitk (master)$ git notes remove 
  Removing note for object HEAD

  # Press F5/ctrl-F5 in gitk.
  # The removed notes are still there.

Best, Gábor
