fdo#72775 : LibreOffice hang while opening some documents

Description: There was a problem for some documents, when opened in LibreOffice
there was continuous increase in page numbers.And this was the reason for LO getting hang.

The wrap property "NS_ooxml::LN_Value_wordprocessingml_ST_Wrap_auto" was not handled in DomainMapper::lcl_attribute() and hence paragraph's wrap property was getting set to
"text::WrapTextMode_NONE" this was the reason for increasing number of pages while opening doc in LO.

added condition to handle NS_ooxml::LN_Value_wordprocessingml_ST_Wrap_auto.

*added test case to verify that the document is opening properly and checking it's page count.
