[BUG] exporting to beamer: notes marked with tag don't work

[Nick Dokos <ndokos@gmail.com>]

If I try to export the following org file to beamer

--8<---------------cut here---------------start------------->8---
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: default
#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) %4BEAMER_col(Col) %8BEAMER_opt(Opt)
#+PROPERTY: BEAMER_col_ALL 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.0 :ETC

* Who/what/how

  - who
  - what
  - how


** Note                                                 :B_note:
   :PROPERTIES:
   :BEAMER_env: note
   :END:
This is a note.
--8<---------------cut here---------------end--------------->8---

with the B_note tag or the B_noteNH tag but *without* the property, the
note ends up as a block in the slide which, according to the doc, is
wrong:

  (info "(org) Beamer class export")

This sentence in particular:

,----
| To simplify note generation, it is actually enough to mark the note with
| a _tag_ (either `:B_note:' or `:B_noteNH:') instead of creating the
| `BEAMER_env' property.
`----

*With* the property, it correctly ends up as a \note{}.
