fdo#80097 : tblBorders and tcBorders are not preserved for the table.

When we have multiple tables inside a table, the tblBorders and
tcBorders of the inside tables are not getting preserved.

The issue is m_aTableStyleConf is not clear when the LO starts
writing the properties of the inside table.
