Fix bug 708659

* Totals column moves to right hand side when periods are added
* Remove unneeded gnc_plugin_page_budget_refresh_cb

Design: in gnc_budget_view_refresh, detect the condition when periods
are added. If this is true, delete the totals column. It will be
regenerated at the end of the refresh function.
