This is grouped aggregate with HAVING in conjunction with a streaming wf
which will initially adds a dummy window. However, the HAVING is pushed
to a table condition: This exercises the try_remove_dummy_windowing_step
which gets called from make_tmp_table_info, so make sure it works on
second execution since we change initial windowing decision made in
setup_windows only during prepare.

Bug: if we have *any* window frame buffers, we need to add any fields
only referenced in expressions to the select list, so they get stored and
restored to/from the window frame buffer; which only uses copy_field.
Unfortunately, we don't know whther we have frame buffer at the time of
setup_fields so we must presume they are always used.
