Since commit c2ccd20c (tdf#44689),
SwWrtShell::InsertPageBreak takes page number as optional argument.
The FN_INSERT_BREAK_DLG case in SwTextShell::Execute expects third
parameter (FN_PARAM_3) to be boolean flag indicating if page number
is filled. But corresponding sw slot was not updated to that fact.
This prevented macros inserting page breaks with page numbers to be
properly recorded, and one couldn't fix that manually, too, because
the slot didn't expect that extra param (which would be dropped in
TransformParameters).

This adds the boolean parameter named PageNumberFilled to the list
of InsertBreak slot.

Unit test included.
