IDEMPIERE-4746 Wrong usage of MTable.getColumnIndex (#640)

* IDEMPIERE-4746 Wrong usage of MTable.getColumnIndex

* Implementing suggestion from Andreas Sumerauer
* Fix issue in IDEMPIERE-3916 (Move Client) and IDEMPIERE-1026 (Create Window from Table)

* IDEMPIERE-4746 Wrong usage of MTable.getColumnIndex

* Change approach to discover real columns

* * Rename method as suggested by Andreas Sumerauer
