tdf#137245 sw: fix AutoFormat SetBorder deleting flys

Since commit e1629c210ad78310e3d48c0756723134a27b89df ReplaceRange()
will preserve flys, so split the delete into a DeleteAndJoin() just to
join the paragraphs - which should not delete any flys because it
doesn't include the "---" so isn't at the end of the section - and
a ReplaceRange for the "---".

(regression from 28b77c89dfcafae82cf2a6d85731b643ff9290e5
and e75dd1fc992f168f24d66595265a978071cdd277)
