tdf#90697 docx - don't change continuous break into page break

As soon as you set PROP_PAGE_DESC_NAME, you are inserting that
style as a page break.  Setting a pagebreak via a continous break
was first introduced in commit 50cb1667020494906afaacb68d4163d1eda527cf
but the unittest for that commit no longer uses this code.
I'm suggesting it be reverted.  It really messes up round-tripping
when continuous breaks are removed/replaced with hard page breaks.

There are a few odd cases where the very first section needs to set the
page break via the continuous break, so it hasn't been eliminated
completely.
