tdf#136956 reorder undo actions in removeColumns
and removeRows. Inside the removeColumns and removeRows, undo actions
are added first, and then cell spans are updated to reflect the removed
columns or rows. Once undo the cell spans they become immediately
invalid because the rows or columns are already removed, hence cause
Impress to crash.
