ScAddress::operator<() is not what we need here, tdf#48140 follow-up fix

ScAddress::operator<() compares by tab,col,row while we need tab,row,col
for ODF import/export.

This caused the export crash tests
http://dev-builds.libreoffice.org/crashtest/27ec6d1cb96a0d3becf14309a26d1c024a0f8603/exportCrash.txt
to fail due to assert

sax/source/expatwrap/saxwriter.cxx:1143: virtual void
{anonymous}::SAXWriter::endElement(const rtl::OUString&): Assertion
`aName == m_pSaxWriterHelper->m_DebugStartedElements.top()'
