fix(flatEntityAccess): getCellDisplayValue now returns the correct value.

* Fix getCellDisplayValue method when using flatEntityAccess, to now return the correct value. Before the cellDisplayGetterCache was just returning the first value cached and ignoring the row parameter

* Add unit tests around get cell value with flatEntityAccess option set
