Subject: Remove useless SinglePar update when scrolling in text

Remove useless SinglePar update when scrolling in text

Using SinglePar does not majke sense here since the paragraph is not
modified and it might even not have a position yet.

This fixes a crash in BufferView::singleParUpdate, which is not
prepared (yet) to such situations.

(cherry picked from commit 2bdd691130e5507fc5cc2ca81e71eef189e90fc5)
