    Header columns can disappear with filtered data in pivot tables
    
    When we set on a pivot table a filter that filters all the rows,
    the pivot table showed only the first header columns and computed
    column, but all the columns headers should still be shown so we can
    adjust the filter for the column. This fixes this issue.
    
    Also add more debug output and prevent a crash when running pivot
    table tests.
