Title: Fix worksheet name escaping and cell sorting in Axlsx.cell_range

We've discovered that Excel do not allow ' in defined_names to
reference a worksheet name. All it does allow is to escape the simple
quote by doubling it. Given that Worksheet#name is escaped using
HTMLEntities, a simple quote appears as ' we simple replace it by
the correct '' when using absolute reference to worksheet range.
