[FIX] sap.ui.table.AnalyticalTable: fixes that column move changes grouping order

- when a column is moved it must be removed from the tables column aggregation and
inserted at the new position. In the analytical table this lead to changing the grouping order
since the grouped columns array was updated. This is fixed now by preventing this update
when the column is moved.
