sw: remove the rLastPaM parameter for SwXText::Impl::ConvertCell()

It is redundant now with pLastCell, and the code updating it looks
highly questionable.

Furthermore ConvertCell() has a post-condition that the last paragraph
in the cell is selected until the end (enforced by split if necessary).
