crashtesting: assert on reexport to ods of forum-it-7248.ods

source document available from:
https://forum.openoffice.org/it/forum/download/file.php?id=7248

The actual cause is already a bad

<table:null-date table:date-value="0000-00-00"/>

imported unchecked. For this, sax::Converter::parseDateTime()
returns a success value, just use it..
If bad keep the default NullDate.
