tdf#96089 sw: fix scope of bBreakAfter in InsertCnt_()

The problem is that bBreakAfter is passed by reference to SwLayHelper
and stored as a reference member there, so it has to live at least as
long as pPageMaker.  (Unfortunately C++ can't statically check that.)

This then somehow caused the number of pages created after initial load
to be 812 instead of the correct 396 determined from the layout-cache in
the bugdoc, and that then caused Drawing objects to move backward during
the following re-pagination, and then SwDrawContact::Changed_() calls
SetFlyFrmAttr() and that sets the document to modified, which triggers the
AutoSave that was reported in the bug.

(regression from b4b7703e4335460cf48bfd6440f116359994c8ff)
