 Creating a new table based on the WP_List_Table class does not work as the
 get_columns method is not being called.

 The problem is when WP_List_Table::get_column_info() calls
 get_column_headers() instead of $this->get_columns() where all the column
 data is stored.

 Moving the filter manage_*_columns from get_column_headers() into
 WP_List_Table::get_column_info() along with passing $this->get_columns()
 fixes this issue.
