small spreadsheet demonstrating the bug

In LibreOffice Calc BASIC macros setting the values of empty cell ranges can not be undone. The new values will remain in the previously empty cells after pressing undo.

Tested functions, undo does not work after these:
targetRange.DataArray = sourceRange.DataArray

Steps to reproduce:
1. create a macro that sets the values in a range of empty cells using the above functions
2. execute the macro
3. press undo

Expected behaviour: the cells content will be erased after undo, restoring their original state.
Actual behaviour: the cells content does not change, the values set by the macro remains there.

See the attached .ods file.

Workaround: set the target cells of the range to empty string before applying the range operation. Do it in an undo context, to have enough undo steps to undo the whole action in one.

Something like this:

	undo = ThisComponent.UndoManager
	undo.enterUndoContext("Copy range action")
	' clear target range, undo workaround
	for row = 4 to 8
		for col = 0 to 1
			sheet.getCellByPosition(col, row).string = ""
		next col
	next row
	copyRange = sheet.getCellRangeByName("A1:B4")
	pasteRange = sheet.getCellRangeByName("A5:B8")
	pasteRange.DataArray = copyRange.DataArray

(Note, clearing the target range with range operation will not work.)

Regression from 3.3, but seen already in 3.5, so not bibisectable.

Severity minor per existing workaround.
