DOCX import: list styles don't support automatic updates

The problem was the following: setPropertyValue("IsAutoUpdate") on the
style failed -> a number of styles was not imported in
StyleSheetTable::ApplyStyleSheets() due to the exception, then when we
tried to use one of the not imported styles, we also got an exception in
DomainMapper_Impl::finishParagraph(), which resulted in not calling
DomainMapperTableManager::handle(), so multiple cells of the same table
wanted the same range for cell contents, and that resulted in a crash.

Regression from cf33af732ed0d3d553bb74636e3b14c55d44c153 (handle
w:gridBefore by faking cells (fdo#38414), 2014-04-23), but that commit
just made the previously hidden problem visible.
