    Fix clutter_table_layout_pack row/column count incrementation.
    
    When appending (with a negative row/column parameter), the row/column
    count should be incremented by 1, not 2. This also fixes layout errors
    when using column/row spacing: The amount of extra space required was
    calculated incorrectly due to the wrong column count.
