Creating a group with just the first row, and then collapse the group causes an exception.

Sample Code:

sheet.groupRow(0, 0);
sheet.setRowGroupCollapsed(0, true);


Caused by: java.lang.IllegalArgumentException: The row number must be between 0 and 65535

Fixed as of r1705844, it seems only the check for row >= 0 was missing, column-grouping seems to be fine in this regard already.
