The view is broken because read_progress_bar() calls read_group() with
two groupbys in eager mode. The method read_group() is overridden for
model `note.note` and does not handle that case: the returned result is
incorrect. We modify the override to call the default read_group() in
that case, which eventually fails and makes read_progress_bar() fall
back on its naive implementation.
