tdf#132822 close open undo group before clearing undo stack
when changing paragraph. previous para undo info needs to be discarded, but
that cannot be done properly if there is an open undo group. So pass the
optional undo group guard down to GetNextSentence_Impl which can close it
before it needs to set the new paragraph.
