tdf#131912 sw: fix spell check correct deleting flys

* SwEditShell::ApplyChangedSentence() should not call
DeleteAndJoin() + InsertString() but ReplaceRange()

* ReplaceRange() and SwUndoReplace need to set a new flag
DelContentType::Replace to tell SwUndoSaveContent::DelContentIndex()
not to delete flys but instead record the previous anchor positions

* SwUndoReplace::UndoImpl() should also not call DeleteAndJoin()
+ InsertString(); instead call ReplaceRange() for the start node
and then DeleteAndJoin() for any regex "\n" that were inserted

(regression from 28b77c89dfcafae82cf2a6d85731b643ff9290e5)
