Deletion of sheet fails
From my previous issue
#27, after fix, there is problem with XlsCommentAreaBuilder.build(). When first 16 out of 17 sheets are deleted immediatelly after the PoiTransformer is created and BEFORE areaBuilder.build(), then IllegalArgumentException is thown.
java.lang.IllegalArgumentException: Sheet index (-1) is out of range (0..0) at HSSFWorkbook.validateSheetIndex(HSSFWorkbook.java:492) at HSSFWorkbook.getSheetName(HSSFWorkbook.java:629) at HSSFSheet.getSheetName(HSSFSheet.java:2052) at PoiTransformer.readCommentsFromSheet(PoiTransformer.java:286) at PoiTransformer.getCommentedCells(PoiTransformer.java:216) at XlsCommentAreaBuilder.build(XlsCommentAreaBuilder.java:132)
Map sheetMap in PoiTransformer.getCommentedCells(line 211) has 17 sheets, but i expect 1 because i deleted other sheets.
