tdf#125688 speed up load of change-tracking ODS

by 10%, by avoiding an OUString construction in a hot path
through
XMLTextColumnContext_Impl::XMLTextColumnContext_Impl
-> sax::Convert::convertNumber

Also changed XMLTextAnimationStepPropertyHdl::importXML
to take advantage of the modified convertNumber passing
convention.
